Why is the toString() method being called when I print an object?

Question

I can\'t seem to understand why when I use println method on the quarter object, it returns the value of the toString method. I never called the toString method why am I g

Answer 1

Because all classes in java are subclasses of java.lang.Object , so whenever you try to call System.out.println() method to print object, it calls the toString() method of Object class.

For Security Reasons the method prints a hashcode, not the values of that object, but you have inherited that method in your class and extended its definition to print object values

public String toString() {
        return "A Quarter is "+getValue();
    }

So you get a return value.
