Override annotation

16 July 2008

Tiger provides many built-in annotation types and Override is one of them. Override should be used only on methods to indicate that the annotated method is overriding a method in a superclass. An example is presented below:

package com.domian.a.test;
 
public class OverrideTester {
 
  public OverrideTester() { }
 
  @Override
  public String toString() {
    return super.toString() + " [Override Tester Implementation]";
  }
 
  @Override
  public int hashCode() {
    return toString().hashCode();
  }
}

In the above example, the @Override annotation annotates two methods toString() and hashCode(). Annotations indicate that these methods are override versions of the methods from the OverrideTester class’s superclass which is java.lang.Object.
