Question

String myString="Plz_help";

I came to know that ‘myString’ is not an object but a object reference variable which stores the base address of the actual object. So ‘myString’ should return an address when i execute

System.out.println(myString);

but it is returning ‘Plz_help’ to the output.

Myclass obj_ref_var=new Myclass();

When I use the same System.out.println(obj_ref_var) for other class which I had created, it is returning the address.

Answer 1

When you call System.out.println on an object reference, system executes toString() method defined for the actual object that this reference refers to. For String this method returns its value.

Apparently, you haven’t defined toString() method for your class that’s why you get object classname + hashcode.
