All variants method overriding

Question

Consider the scenario where we have two classes related by inheritance

class Parent {    
}

class Child extends Parent{   
}

1. If Parent declares a method with folowing signature:

   public String method(Number n) / /parent 1
   

   I know that in Child I can declare method with following signature(should be override)

   public String method(Number n) // chilld 1_1
   

2. But if Parent contains following signature:

   public <T extends Number> String method(T t) //parent2
   

   Child can override it by following signatures(2, separated):

   public String method(Number n)//chilld 2_1
   

   or

    public<T extends Number> String method(T t)// chilld 2_2
   

Are there other variants for overriding parent1 or parent2 ?

Answer 1

If you are only looking for a variant then how the following -

public String method(Number n) throws RuntimeException

or,

public <T extends Number> String method(T n) throws RuntimeException

---

Also, the other that don't apply in case of String, because it's final, is that the overriding methods are allowed return a subtype of return type in the parent.
