After logging in, type “java developer package” in the search field (see screenshot).The cleanest way to manage multiple java versions on Mac is to use Homebrew. Fortunately, it’s free but you still need to register it. You’ll need an AppleID to download the JDK. The JDK for Mac OS X comes as “Java Developer Package”.
Eclipse doesn’t ship with the Java source code though.
That’s why you don’t need to install a JDK to create Java programs with Eclipse. Remark: Eclipse comes with its own Java compiler. The JDK includes the JRE, and also comes with Java’s source code. JDK: The “Java Development Kit” is required when you want to compile Java programs. You cannot, however, compile Java programs with just the JRE. JRE: The “Java Runtime Environment” is necessary to run Java application.
When working with Java, you need to distinguish two Java software package types: That’s the “Java version” you need to know.
