java - How do I override a parent class's method? -

import java.io*; import java.awt.*; import java.util.concurrent.*;  public class studentqueue<e> extends arrayblockingqueue<e> {     public studentqueue(int capacity)     {         super(capacity);     } } 

how override corresponding parent class's methods? need override methods in java library arrayblockingqueue. how go implementing own method , having override method in parent class?

any example do, not have arrayblockingqueue. please , thank you.

if method has same name parent's, parameters , return type, you're overriding it. can add @override annotation on top of method.

always check parent's method not final nor private.

for instance

public class parent{   public void method(string param){     //do stuff   }    private void notextendable(string param){    }    protected void alsoextendable(string param){    } }  public class subclass extends parent{   @override   public void method(string param){     //super.method() //if want execute parent's method     //do own stuff   } }
