Learning by examples
We use the @Override annotation as part of method declaration. The @Override annotation is used when we want to override methods and want to make sure have overriden the correct methods.
As the annotation name we know that there should be the same method signature in the parent class to override. That means using this annotation let us know earlier when we are mistakenly override method that doesnât exist in the base class.

Code:

package org.kodejava.example.annotation;  
  
public class OverrideExample {  
    private String field;  
    private String attribute;  
  
    @Override  
    public int hashCode() {  
        return field.hashCode() + attribute.hashCode();  
    }  
  
    @Override  
    public String toString() {  
        return field + " " + attribute;  
    }  
}
