(1) Block selection mode: works for cut, copy, and paste.



(2) Go to the implementation of an interface method.


(3) Better completion of inner interface implementations: When completing an interface such as Runnable, stubs for the methods are created immediately (instead of on demand, via a quick fix, as a second step).

   public static void main(String[] args) {
        new Runnable() {
           
            public void run() {
                // TODO Auto-generated method stub
               
            }
        };
    }

(4) “Invert if” quick fix (when the cursor is on the “if” keyword). Turns
   public static void main(String[] args) {
       if (args.length == 0) {
           System.out.println("Need at least one argument.");
       } else {
           processArguments(args);
       }
   }

into

   if (args.length != 0) {
       processArguments(args);
   } else {
       System.out.println("Need at least one argument.");
   }

(5) Improved systrace for inner classes. Completing the word “systrace” inserts a system.out.println() with the name of the current method (if you do println debugging, you’ll always find where the printing happens). Prior to 3.5, this did not work well for inner classes. This has been fixed:

   public static void main(String[] args) {
       new Runnable() {
           public void run() {
               System.out
                       .println("SidebarPanel.main(...).new Runnable() {...}.run()");
           }
       };
   }
