Java has been implemented by using the javac.exe from commandline (with Process.Start()) - Can be improved by using an API (e.g: create JNI Interface which will call a Java compiler in Java (JavaCompiler))

Implementation / Compiler

You can write small snippets, but be aware: Fiddle will automatically put them into a main method if none found.

So:

System.out.println("Hello world!");

Will be compiled as:

public class FiddleClass {
    public static void main(String[] args) {
        System.out.println("Hello world!");
    }
}

You cannot use any Globals in your code so far.

• string jdkPath: Path to Java Development Kit. If empty, Fiddle will automatically search the JDK in Program files or Environment variables
