To use Eclipse for Java programming, you need to first install Java Development Kit (JDK). Read "How to Install JDK for Windows".

Step 1: Download

Download Eclipse from https://www.eclipse.org/downloads. Under "Get Eclipse IDE 2019-12" ⇒ Click "Download Packages". For beginners, choose the "Eclipse IDE for Java Developers" and "Windows 64-bit" (e.g., "eclipse-java-2019-12-R-win32-x86_64.zip" - about 201MB) ⇒ Download.

Step 2: Unzip

To install Eclipse, simply unzip the downloaded file into a directory of your choice (e.g., "c:\myProject").

I prefer the zip version, because there is no need to run any installer. Moreover, you can simply delete the entire Eclipse directory when it is no longer needed (without running any un-installer). You are free to move or rename the directory. You can install (unzip) multiple copies of Eclipse in the same machine.

Perspectives

In Eclipse, a perspective provides initial layout that is organized to help programmers accomplish a task or work. Each perspective contains a different set of editors and views. For example, the Java perspective contains the following editors and views:

- Java Editors: for editing Java source files.

- Package Explorer: allows you to navigate the projects.

- Outline: displays the structure of source file in the active editor.

- Problems: shows errors, warnings and problems detected.

- Javadoc: allows you to preview Javadoc of a class, method, field…

- Declaration: shows declaration statement for the variable at the cursor position.

- Task List: displays tasks downloaded from a popular bug tracker tool like Bugzilla, Mantis…

The following screenshot is of a Java perspective:

When you are working in the perspective, you and open more editors and views when needed, but initially a perspective contains a fixed set of editors and views. The toolbars and menu items are also changed according to the purpose of the current active perspective.
