Difference Between Method Overloading and Overriding with Example

Method Overloading	Method Overriding
Method overloading is used to increase the readability of the program.	Method overriding is used to provide the specific implementation of the method that is already provided by its super class.
In case of method overloading, parameter must be different.	In case of method overriding, parameter must be same.
Method overloading is performed within class.	Method overriding occurs in two classes that have IS-A (inheritance) relationship.
Method overloading is the example of compile time polymorphism.	Method overriding is the example of run time polymorphism.
In java, method overloading can’t be performed by changing return type of the method only. Return type can be same or different in method overloading. But you must have to change the parameter.	Return type must be same or covariant in method overriding.

Examples : 

Method Overloading

class OverloadingExample{

static int add(int a,int b){return a+b;}

static int add(int a,int b,int c){return a+b+c;}

}

Method Overriding 

class Animal{

void eat(){System.out.println(“eating…”);}

}

class Dog extends Animal{

void eat(){System.out.println(“eating bread…”);}

}
