Hello Friend,

class Test {
    public void display(String msg) {
        System.out.println(msg); 
        }
        public void display(Object msg) { 
            System.out.println(msg);
            }

}
class TestDemo { 
    public static void main(String[]args){
    new Test().display(null);
    }
}

The above code displays the output null as we have called the method display() of Test class and passed null as the parameter.

Thanks
