Overview of the Eclipse IDE

Introduction

To use the Eclipse IDE, you will need to install the correct version that is suitable for your device first and foremost. Once you launch the Eclipse IDE, you will have to set a workplace. This is a directory of your machine where all the future projects and programs that you type on Eclipse will be saved. If you are a first-time user, you can take a simple tour by clicking on the ‘Overview’ button.

Appearance

You can configure the appearance or theme of the interface. By default, Eclipse is set to a light theme. You can change it to a dark theme by going to Preferences > General > Appearance > Dark.

Perspective

As Eclipse is a cross-language IDE, you have to have a divide between the languages you are using. The perspective feature in IDE sets the application to process code according to the syntax of a certain language. As we are dealing with JAVA, you should set your perspective to JAVA. You can change to another perspective by navigating to Windows + Perspective > Open Perspective > Other.. menu entry. Use the Window > Show View > Other menus to open a new part in your current perspective.

Eclipse Java Perspective

The Package Explorer contains the current project that you are working on. The View Menu on the Toolbar allows you to view the components of the package. You can double click on a class to open it up on the editor. In the Outline view, you will be able to see the source file currently selected. The Problems View works like a database that lists all the compile-time errors in your code. To open it, go to Window > Show View > Problems.

The Java Editor is the space where you type in your code. Each class opens up on a new editor and you can edit the appearance
