Method overriding on the other hand is declaring a method in subclass which is already present in parent class. The subclass can then provide an implementation. An example is ovveriding the toString() or equals() methods from the Object superclass and then providing specific implementation of the methods in your class. Second difference is that Overloading happens at compile-time while Overriding happens at runtime: The binding of overloaded method call to its definition has happens at compile-time however binding of overridden method call to its definition happens at runtime.
