如何从子类调用重写的父类方法？ [英] How do I call an overridden parent class method from a child class?

问题描述

如果我有一个子类，它有从父类重写的方法，并且在非常特殊的情况下我想使用原始方法，我该如何调用这些方法？

If I have a subclass that has methods I've overridden from the parent class, and under very specific situations I want to use the original methods, how do I call those methods?

推荐答案

调用超级

class A {
   int foo () { return 2; }
}

class B extends A {

   boolean someCondition;

   public B(boolean b) { someCondition = b; }

   int foo () { 
       if(someCondition) return super.foo();
       return 3;
   }
}
