For a Java developer, you must choose any IDE to write your Java code. For example, you can download and install Eclipse, Netbeans, or jet-brain to write Java code.
You first need to write on your internet explorer search bar 'eclipse download'; it will take you to the Eclipse.org website; from there, you can choose your desired version of eclipse.
For Java developers and the new Java programmer, you choose either eclipse for Java developers or eclipse for Java enterprise. I recommend that you download eclipse for Java enterprise edition. Then, in that IDE, you do both and create excellent Java programs and a Java web application.
In this video, you can find out how to download and install eclipse on your windows device.
