Whats does @Override mean?

Question:

Whats does @Override mean?

Answer:

The override annotation (@Override) indicates that a method declaration intends on overriding a method declaration in the classes supertype.

When overriding a method, you might want to use the @Override annotation that instructs the compiler that you intend to override a method in the superclass. If, for some reason, the compiler detects that the method does not exist in one of the superclasses, then it will generate an error.

Code:

public class Animal {
 
   public void speak(){
   }    
 
}
 
class Cat extends Animal{
   @Override
   public void speak(){
      System.out.println("meow");
   }    
}
