@Override

Hi,

So there are basically two things happening. One, you are overriding an already created method. Second, the annotation @Override provides safety because when the code is ran it will be double checked that you are indeed overriding an already made method.

For example, you have a class named Animal (the superclass) and you create a subclass called Dog. Since the Dog class is a subclass of the Animal class (the dog's superclass) you may want to use a method from the Animal class. A way to do that is to use the @Override annotation.

Here is a link with some examples. http://www.codejava.net/java-core/the-java-language/override-annotation-examples

Hope this helps.

most of the time you will see @Override annotation with the following methods but there are many , i have to example down

toString

which is inherited from Object class

 public String toString() {
        return getClass().getName() + "@" + Integer.toHexString(hashCode());
    }

so we put Override to use our method instead of the Object.java (super class) toString method

we can change it to this code instead

@Override
    public String toString() {
        return "HelloWorld{}";
    }

equals

also can be inherited from Object class

public boolean equals(Object obj) {
        return (this == obj);
    }

so we can change it to this method below here, instead of using Object.java method , the override annotation will make the compiler to use the annotated 1 with Override instead of using the non-annotated method

@Override
    public boolean equals(Object obj) {
        return super.equals(obj);
    }
