Function override-overload in Java

Question

What is the difference between override and overload?

Answer 1

Overloading :

public Bar foo(int some);
public Bar foo(int some, boolean x);  // Same method name, different signature.

Overriding :

public Bar foo(int some);   // Defined in some class A
public Bar foo(int some);   // Same method name and signature. Defined in subclass of A.

If the second method was not defined it would have inherited the first method. Now it will be replaced by the second method in the subclass of A.
