The @Override annotation is a standard Java annotation that is used to indicate that a particular method is intended to override a method with the same signature in a parent class or interface.

When you annotate a method with @Override, you are telling the Java compiler that the method is meant to override a method in a parent class or interface, and that you expect the method signature to match the signature of the parent method.

Here is an example of how to use the @Override annotation:

public class MySubclass extends MySuperclass {

  @Override
  public void myMethod() {
    // method body
  }

}

In this example, MySubclass is a subclass of MySuperclass, and it overrides the myMethod() method from the parent class. The @Override annotation is used to indicate that the method is intended to override the parent method.

When you use the @Override annotation, the Java compiler will check that the method signature in the subclass matches the method signature in the parent class or interface. If the signatures do not match, the compiler will produce an error, indicating that the method is not a valid override. This helps to catch errors early in the development process and ensures that your code is correct and maintainable.
