Method Overriding in Java

Method Overriding in Java:

                                             We studied about method overloading in Java.Now the next is Method Overriding in Java. Here the number of arguments and datatype and all are same.

1. Used in parent class and child class.
2. Parent class method is Overriding by Child class.
3. number of arguments are same.
4. datatype of arguments are also same.
5. Method name is same.
6. The example is when a method in a Interface have to behave differently in different scenarios.

Example:

package com.jobberindia;

public interface Test {
void performSomeTask(int a,int b);
}

           
package com.jobberindia;
import java.io.File;
import java.util.*;
public class HelloWorld implements Test{

@Override
public void performSomeTask(int a, int b) {
// TODO Auto-generated method stub
System.out.println("subtracting "+a+" from "+b+" is: "+(a-b));
}

public static void main(String[] args) {
Test t =  new HelloWorld();
t.performSomeTask(55, 15);
}
}
