What is the difference between Method overloading and method overriding ?

Answer 1

Overload
class A{
public void x( ){
// I am method x
}

public void x(int i){
// I am overloading of method x
}
}

Override
class B extends A{
public void x( ){
// I am overridding of method x of class A
}
}

Overloading occurs when two or more methods in one class have the same method name but different parameters. 

Overriding means having two methods with the same method name and parameters (i.e., method signature). One of the methods is in the parent class and the other is in the child class.

Answer 2

don't forget to place @override in front of the method to make your code more readable. and easier to understand that it's overriding another method

Answer 3

here is an example that you may want to check to see difference or understand the meanings of overriding and overloading https://code.sololearn.com/c0awDMpDLukF/?ref=app

Answer 4

to add with what Scott wrote here ...annotation is also helpful to generate documentation.

Answer 5

Method overloading deals with the notion of having two or more methods in the same class with the same name but different arguments.

Method overriding means having two methods with the same arguments, but different implementations. One of them would exist in the parent class, while another will be in the derived, or child class. The @Override annotation, while not required, can be helpful to enforce proper overriding of a method at compile time.

Answer 6

method overloading is performed in same class
a method can be overloaded by changing its signature
whereas overriding performed in different class
there should be is-a(inheritance ) relationship between classes to perform overriding

Answer 7

I have a question plz! Can you tell me if overloading can occurs by methods from different class? Or should it be only from the same class?
