    // Test Overriding
    public static void main(String[] args) {
        SuperClass obj = new SubClass();
        System.out.print(obj.greeting);
        obj.displayName();

// After compile, run java SubClass, we get output
Hello SubClass

?So, only methods are overrided. (properties don’t change)
