Method Overriding in Java Example

Overview

An instance method in a child class that has the same method signature of the parent class is sail to be overriding the parent’s class method. Using this feature we can provide a child-specific implementation for the method. We can use the @Ovevrride annotation when we are overriding the method.

Method signature  =  access specifier <method return type> name of the method( method parameters)

 

Coding Listing

/**

 */
package com.testingdocs.tutorial;

/**
 * @author TestingDocs

 */
public class Document {
  public void printDoc() {
    System.out.println("Print Parent Document...");
  }
}

 

Child class

package com.testingdocs.tutorial;

public class TestPlan extends Document {

  @Override
  public void printDoc() {
    //Overridden method 
    System.out.println("Print Child TestPlan...");
  }

  public static void main(String[] args) {
       TestPlan tp=new TestPlan();
       tp.printDoc();
  }
