You created your first Java project, a package, a Java class and you ran this program inside Eclipse. A JAR file is the standard distribution format for Java applications. Select JAR file and select the Next button. Select your project and enter the export destination and a name for the JAR file, for example myprogram.

Press The Finish button. This creates a JAR file in your selected output directory. Open a command shell, e. This should open a console window. Switch to the directory which contains the JAR file, by typing cd path. To run this program, include the JAR file in your classpath.

The classpath defines which Java classes are available to the Java runtime. You can add a JAR file to the classpath with the -classpath option. Type the above command in the directory you used for the export and you see the “Hello Eclipse!

This is a simple class without the usage of any unit testing framework like JUnit. The Eclipse editor should mark the created class with an error because the required import statements are missing.

Right-click in your Java editor and select Source Organize Imports to add the required import statements to your Java class. This should remove the syntax error.

Finish the implementation for the Tester class based on the following code. Finish the source code and calculate the correct values. Run the Tester class and validate that your implementation is correct. The Tester class checks for an example value but the method should work for different input values.

You can export and import Eclipse projects. This allows you to share projects with other people and to import existing projects. You can import from an archive file, i. Export your one of your projects into a zip file. Switch into a new workspace and import the project into your new workspace based on the zip file you exported.

The primary way of navigating through your project is the Package Explorer or alternatively the Project Explorer view.

You can open nodes in the tree and open a file in an editor by double-clicking on the corresponding entry in the tree hierarchy. The drop-down menu in the Package Explorer allows you to filter the resources which should be displayed or hidden.

The Package Explorer view allows you to display the associated file from the currently selected editor. For example, if you are working on the Foo.

To activate this behavior, press the Link with Editor button in the Package explorer view as depicted in the following screenshot. You can navigate between the classes in your project via the Package Explorer view as described before. You can navigate the tree and open a file via a double-click. In addition, you can open any class by positioning the cursor on the class in an editor and pressing F3.

This shows the following dialog in which you can enter the class name to open it. You can also search for package names. Each part of the package name must end with a. You can open any file from your open projects via the Open Resource dialog. This dialog allows to enter the file name and to open or show it in a selected view. The following screenshot demonstrate the usage to open a pom.

Quick Outline shows you an structured overview of the file you are editing. For example, for a Java class you see its methods with the option to filter. You can also reach this option, via right-click in an editor via the Quick Outline option.

By default, Quick Outline shows only the direct members and fields of the Java class. The default look of the Quick Outline option is similar to the Quick Outline view of the Java perspective. The type hierarchy of a class shows you which classes it extends and which interfaces it implements. You can use the type hierarchy to navigate to one of these elements. You frequently need to find files containing certain text or other meta data.

Use the File Search tab to search for text with the option to use regular expressions and also to replace matching entries. Eclipse associates file extensions with the default tab.

You can customize the available search tabs via the Customize button in the Search dialog. Via the Remember the last used page you can configure Eclipse to use your last tab as default. For example, use the Java Search tab to search for Java elements, e.

The Search view shows the search results for the selected scope. You can double-click on a search entry to navigate to the corresponding position in the editor. The currently selected search result is also indicated via an arrow in the left border of the editor.

This allows you to search in the current active editor for a text which is displayed in the status line as depicted by the following screenshot. The advantage of this search is that no pop-up dialog is opened which blocks other elements in the Eclipse IDE. You can also navigate via the annotation buttons, e.

By pressing the buttons you can navigate to the related annotations. The following screenshot shows source code with two warnings and one error and you can navigate between the corresponding code via the annotation buttons. Which annotations are relevant for navigation can be configured via the drop-down menu of the toolbar.

This selection is highlighted in the following screenshot. In a lot of cases you can also use the mouse to navigate to or into an element if you press the Ctrl key. For example, press the Ctrl key and left click with the mouse on the name of a class to jump into the class declaration.

Similar to the left mouse click combined with the Ctrl , you can use the F3 key to go into a class. You can also activate the breadcrumb mode for the Java editor which allows you to navigate the source code directly from the Java editor. You can activate this mode via right-click in the editor and by selecting the Show in Breadcrumb entry. This allows you to navigate the source code from the editor as depicted in the following screenshot.

There are a lot of shortcuts available for navigation. Closing projects saves memory in Eclipse and can reduce the build time. Eclipse ignores closed projects, e. Also the Problems view does only shows errors of opened projects. This typically helps you focus your attention on the project. You can close projects via a right-click on it and by selecting the Close Project menu entry. Alternatively, if you work on a project, you can close all unrelated projects via a right-click on it and by selecting the Close Unrelated Projects menu entry.

You can use the filter functionality for the Package Explorer view to hide the closed projects. Content assist is a functionality in Eclipse which allows the developer to get context-sensitive code completion in an editor upon user request. This will replace syso with System. If you have a reference to an object, for example, the object person of the type Person and need to see its methods, type person. Whenever the Eclipse Java tooling detects a problem in your code, it underlines the problematic text in the editor and create a problem marker.

The problem marker is visible in the Problems View and in the editor via markers on the left side of the editor. This functionality is called Quick Fix. Eclipse suggests creating a field or local variable.

Quick Fix is extremely powerful. For example, it allows you to create new local variables and fields as well as new methods and new classes. It can also assign a statement to a variable and much more. Quick Fix also gives several options for code changes on code which does not contain errors, e. This section demonstrates the quick fix for converting anonymous inner classes to lambda expressions.

Eclipse has several possibilities to generate code for you. This can save significant time during development. For example, Eclipse can override methods from superclasses and generate the toString , hashcode and equals methods. It can also generate getter and setter methods for attributes of your Java class.

To test the source generation, create the following class in your com. In this exercise you practice the usage of code generation and the usage of the Content Assists functionality.

Use the Source Generate Getter and Setter to create getters and setters for all fields. Use Eclipse to generate a toString method for the Todo class based on the id and summary field. Also generate a hashCode and equals method based on the id field. Create a new class called TodoProvider. Create the following static method in your TodoProvider class. Write another TodoProviderTest class with a public static void main String[] args method.

In your main method call the createInitialModel method and validate that the returned number of items is 5. If another number than 5 is returned, throw a RuntimeException. If the correct number is returned, write the String “Correct” to the Console view.

Use Content assist to create the System. While this exercise was about code generation and content assists, you might be interested in a potential solution for this exercise. The following listing contains a potential solution. This section covers the refactoring facilities of Eclipse which allow you to improve the structure of your source code. Refactoring is the process of restructuring the code without changing its behavior.

For example, renaming a Java class or method is a refactoring activity. For example, to use the Rename refactoring, you can right-click on your class in the editor or Package Explorer and select Refactor Rename to rename your class.

Eclipse will make sure that all calls in your Workspace to your class or method are renamed. The following screenshot shows how to call the Rename refactoring for a class. The cursor is positioned on the class and the context menu is activated via a right-click on the class.

Gives magic numbers or hard-coded strings a descriptive constant name and replaces all occurences. Eclipse has many more refactorings. The available options depend on the selection in the Java editor. In most cases you should get an idea of the performed action by the naming of the refactoring operation.

A useful refactoring is to mark code and create a method from the selected code. Mark now the coding of the “for” loop, right click on the selection and select Refactoring Extract Method. Use calculateSum as the name of the new method.

You can also extract strings and create constants based on the strings. Mark for this example the “Hello Eclipse! Eclipse provides a lot of shortcuts to work efficiently with the IDE. For a list of the most important Eclipse shortcuts please see Eclipse Shortcuts. You can store JAR files directly in your project, and add them to the classpath which the Java compiler of Eclipse is using. To manage the classpath for your Eclipse, right-click on your project and select Properties.

Under Java Build Path Libraries you can review and change your current classpath as depicted in the following screenshot. JAR files can be stored outside your project or inside. Select the Java library you want to import and select the folder, e. Alternatively, to the import approach via the menu, you can copy and paste the jar file into a folder. You can define in Eclipse that a project is dependent on another project.

If you do this, you can use its classes in the project defining the dependency. To do this select your project, right-click on it and select Properties. Select Java Build Path and the Projects tab.

This only works within Eclipse, it allows you to develop several projects which will later be exported as JAR files together. Outside of Eclipse you need to create Java libraries for the projects and add them to the classpath. You can open any class by positioning the cursor on the class in an editor and pressing F3. This shows a dialog in which you can enter the class name to open it.

This happens, for example, if you open a class from a the standard Java library without attaching the source code to it. To see the source code of such a class, you can attach a source archive or source folder to a Java library.

Afterwards, the editor shows the source instead of the bytecode. To open this page, right-click on a project and select Properties Java Build Path.

The following screenshot shows this setting for the standard Java library. The file is typically called src. It is also possible to add Javadoc to a library which you use.

For this you need to have the Javadoc somewhere in your filesystem. Select Properties Java Build Path. The Eclipse IDE allows you to install and update software components.

The Eclipse update functionality only downloads new or updated components. Installable software components are located in update sites.

Update sites can be located on a web server or on the file system. If you are behind a network proxy, you have to configure your proxy via the Window Preferences General Network Connection preference setting.

Otherwise, Eclipse may not able to reach the update sites. To update your Eclipse installation, select Help Check for Updates. The system searches for updates in the configured update sites for the installed software components. If it finds updated components, it will ask you to approve the update. From the Work with list, select or enter a URL for the update site you want to use. And not categorized items are only displayed if the grouping is disabled.

After an update or an installation of a new software component, you should restart Eclipse to make sure that the changes are applied. Eclipse contains a client which allows installing software components from the Eclipse marketplace. The advantage of this client is that you can search for components, discover popular extensions and see descriptions and ratings.

Compared to the update manager, you do not have to know the URL for the software site which contains the installable software components. Most Eclipse distributions contain the Marketplace client by default. You may need to install the Marketplace client software component into Eclipse before you can use it. You can use the Find box to search for components. Pressing the Install button starts the installation process. The marketplace client allows to install your favorite plug-ins directy.

For this, go to the Eclipse Marketplace website and login with your Eclipse. Afterwards, select the Favorites tab in the Eclipse Marketplace client and login to be able to install your favorites. Eclipse plug-ins are distributed as jar files. If you want to use an Eclipse plug-in directly or do not know the update site for it, you can place it in the dropins folder of your Eclipse installation directory.

Eclipse monitors this directory and during a re- start of your IDE, the Eclipse update manager installs and removes plug-in based on the files contained in this directory. You should not modify the content of the Eclipse plugins directory directly. If you want to install plug-ins, put them into the dropins folder.

If you want to remove it, delete the JAR from this folder. Plug-ins are typically distributed as jar files. To add a plug-in to your Eclipse installation, put the plug-in. Eclipse should detect the new plug-in and install it for you. If you remove plug-ins from the dropins folder and restart Eclipse, these plug-ins are automatically removed from your Eclipse installation. Eclipse allows you to export a file which describes the installed Eclipse components.

During the export the user can select which components should be included into this description file. Other users can import this description file into their Eclipse installation and install the components based on this file. Select the components which should be included in your description file. To install the described components in another Eclipse installation, open the exported file with File Import Install Install Software Items from File and follow the wizard.

The wizard allows you to specify the components which should be installed. The Eclipse update manager has a component called director which allows you to install new features via the command line. You need to start this command in the command line and it assumes that you are in a directory which contains your Eclipse installation in a folder called eclipse.

The feature names which you need for this operation can be seen on the second page of the standard installation dialog of the Eclipse update manager. The behavior of the Eclipse IDE can be controlled via key value pairs stores as preference settings.

Each Eclipse software component can define such perferences and use the values to configure itself. This allows you for example to configure how long the Eclipse waits before the code completion or if the import statements in your source code should be automatically adjusted if you save your source code.

Which preferences are key values stored on the file system, the Eclipse IDE allows the user to configure most of these values via the preference dialog. Select Window Preferences to open the preference dialog. You can use the filter box to search for specific settings.

Correctly configuring Eclipse to your needs can largely improve your productivity. Most of these preference settings are specific to your workspace but some are also valid for all workspaces. In this file you enter default values for preference settings. For example, the following will setup a default type filter for the java. The following example eclipse.

To identify a key for a certain preference setting you can export existing preference settings via the following approach. The Eclipse IDE is relatively conservative configured to avoid surprises during development.
