method overloading and method overriding

In Java, there are numerous distinctions between method overloading and method overriding. The following is a list of the differences between method overloading and method overriding:

No.Method OverloadingMethod Overriding
1)To make the program more readable, method overloading is used.Method overriding is used to provide a specific implementation of a method that its superclass already provides.
2)Within a class, method overloading is done.Method overriding occurs in two classes that have IS-A (inheritance) relationship.
3)When overloading a method, the parameter must be different.When overriding a method, the parameter must be the same.
4)Compile-time polymorphism is demonstrated by method overloading.Run-time polymorphism is demonstrated by method overriding.
5)In Java, method overloading is not possible by simply changing the method’s return type. In method overloading, the return type can be the same or different. However, you must alter the parameter.In method overriding, the return type must be the same or covariant.
