What version of Java is running in Eclipse?

Question

How do I know what version of Java is being run in Eclipse?

Is there a way to write code to find out?

Is "JRE System Library [JavaSE-1.6]" in "Package Explorer" the right version?

Answer 1

If you want to check if your -vm eclipse.ini option worked correctly you can use this to see under what JVM the IDE itself runs: menu Help > About Eclipse > Installation Details > Configuration tab. Locate the line that says: java.runtime.version=....

Answer 2

The one the eclipse run in is the default java installed in the system (unless set specifically in the eclipse.ini file, use the -vm option). You can of course add more Java runtimes and use them for your projects

The string you've written is the right one, but it is specific to your environment. If you want to know the exact update then run the following code:

public class JavaVersion {   public static void main(String[] args) {     System.out.println(System.getProperty("java.runtime.version"));   } }
