Garbage collector is not running

I understand that we cannot guarantee that garbage collector is called in java.

public class finalizeDemo {
    protected void finalize() {
        System.out.println("Wow!! I am called");
    }
}

class testFinalizeDemo {
    public static void main(String[] a) {
        finalizeDemo obnj = new finalizeDemo();

        System.gc();
        /**
         *  Forcefully call garbage collector.
         */
    }
}

But I read that System.gc() will invoke gc forcefully. But my statement is not getting printed in my local eclipse.

Does anyone know why the statement isn't being printed?
