Method Overriding in Java Example

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();
 }

}
