overloading and overriding

What is the difference between method overloading and method overriding in Java?

Differences between method overloading and overriding are:

• Method overloading is static polymorphism. Method overriding is runtime polymorphism.
• Method overloading occurs within the same class. Method overriding happens in two classes with hierarchy relationship.
• Parameters must be different in method overloading. Parameters must be same in method overriding.
• Method overloading is a compile time concept. Method overriding is a runtime concept.
