Operator overloading and overriding in Java

Question

What is the difference between operator overloading and operator overriding?

Are they the same in inheritance and console program?

Answer 1

You can overload operator in C++ but not in Java. I wonder if you meant method overloading and method overriding? Method overloading is having two definitions for the same method signature. For example,

int sum(int var1, int var2)
{
  return (var1+var2);
}

int sum(int var1, int var2, int var3)
{
  return (var1+var2+var3);
}

In object oriented programming, you override (redefine) a function that is inherited from ascendant (base) class. In a class hierarchy, when a function (method) in a subclass has the same name and type signature as a method in its superclass, then the method in the subclass is said to override the method in the superclass.
