Question

Answer 1

If you really need to throw an exception without surrounding your code with a try and catch

@override
public String toString(){
     if(...)throw new IllegalStateException("list is empty");
     else if(...)throw new IllegalStateException("position is invalid"); 
     return ...;
}
