How to start using Eclipse 2021-09
After you have installed Eclipse 2021-09, you can start using it for your development projects. Here are some basic steps to get started:
Creating a workspace and a project
A workspace is a folder where Eclipse stores your projects and settings. A project is a collection of files and resources that are related to a specific development task. To create a workspace and a project, follow these steps:
When you launch Eclipse for the first time, it will ask you to select a workspace location. You can use the default location or browse to a different one. You can also check the option to use this as the default and do not ask again if you do not want to see this dialog again.
Click the Launch button to open the Eclipse workbench, which is the main user interface of Eclipse. You will see different views and editors that allow you to work with your projects and files.
To create a new project, go to File > New > Project and select the type of project that you want to create. For example, if you want to create a Java project, select Java Project under Java category.
Click the Next button and enter a name for your project. You can also change other options, such as the location, the Java version, the source folders, etc.
Click the Finish button to create your project. You will see your project in the Package Explorer view on the left side of the workbench.
Configuring preferences and settings
You can customize Eclipse to suit your preferences and needs by changing various options and settings. To access the preferences dialog, go to Window > Preferences. You will see a tree of categories on the left side and a panel of options on the right side. You can expand or collapse the categories and select the ones that you want to modify. For example, if you want to change the font size of the editor, go to General > Appearance > Colors and Fonts and select Text Font under Basic category. You can then click the Edit button and choose a different font size.
Exploring the user interface and tools
Eclipse has a rich and flexible user interface that allows you to work with your projects and files in different ways. You can explore the following elements of the user interface and tools:
The workbench is divided into different areas called perspectives, which are collections of views and editors that are relevant for a specific task. For example, the Java perspective contains views and editors for editing Java code, debugging Java applications, browsing Java packages, etc. You can switch between different perspectives by clicking their icons on the top right corner of the workbench or by going to Window > Perspective > Open Perspective.
The views are windows that show information or provide actions related to your projects and files. For example, the Package Explorer view shows the structure and contents of your Java projects, the Problems view shows errors and warnings in your code, the Console view shows the output of your running applications, etc. You can open, close, move, resize, or dock views by using the toolbar buttons or the context menu of each view.
The editors are windows that allow you to edit your files and code. For example, the Java editor provides syntax highlighting, code completion, error detection, refactoring, formatting, and other features for editing Java code. You can open, close, save, or switch between editors by using the toolbar buttons or the tabs on the top of each editor.
The toolbar is located on the top of the workbench and contains buttons for common actions and commands. For example, you can use the toolbar to run, debug, or terminate your applications, to undo or redo your changes, to search or replace text, to switch perspectives or views, etc. You can customize the toolbar by right-clicking on it and selecting Customize Perspective.
The menu bar is located on the top of the workbench and contains menus for accessing various options and functions. For example, you can use the menu bar to create new projects or files, to import or export resources, to configure preferences or settings, to access help or documentation, etc. You can also access some of the menu items by using keyboard shortcuts.
The status bar is located on the bottom of the workbench and shows information about the current state of Eclipse. For example, it shows the progress of background tasks, the memory usage of Eclipse, the line and column numbers of the cursor position in the editor, etc. You can also click on some of the icons on the status bar to perform actions or change settings.
