        Box<Integer> integerBox = new Box<Integer>();
        integerBox.set(new Integer(100));
        //integerBox.set("Ram"); //Compile time error
        Integer integerValue = integerBox.get();
        System.out.println("integerValue = "+integerValue);

        Box<String> stringBox = new Box<String>();
        stringBox.set("Peter");
