Why is it possible to delete an exception "release" statement from the signature of an inherited method?

Question

I would like to know because I did not understand this part, it is because it is a statement that it can "launch" an exception?

//EXEMPLO
public abstract class Personagem{
    public abstract void atacar() throws Exception;
}
//Atacar é abstrato
//logo abaixo quando eu herdo eu posso tirar o throws Exception da assinatura.
public class Mago extends Personagem{
    public void atacar(){
    }
}

Answer 1

The method atacar() is being overwritten in the subclass Mago, that is, the method is not invoked in the superclass Personagem and shall not make an exception.
