问题描述

有没有办法禁止子类在java中调用超类的公共方法？

Is there any way to forbid the son class to call the public method of super class in java?

例如

public abstract class TObject{
    abstract public void quark();
}


public class Animal extends TObject{

       public void quark(){
           System.out.println("this is the animal");
       }

}

public class Dog extends Animal{
       @overide
       public void quark(){
           System.out.println("this is the animal");
           **super.quark();**
       }
} 

In this example, The Dog call the **super.quark();** in it's quark method.

但我不希望Dog可以调用 super.quark（）; 我也不想将Animal中夸克方法的

But I don't want the Dog could call super.quark(); and I also don't want to change the

修饰符更改为私有。有没有办法在编译时阻止这种情况？

modifier of quark method in Animal to private. Is there any way to prevent this in compile?

我这样做的原因是我在开发 hudson scm插件时遇到了类似的问题。我

覆盖超类的公共方法，然后调用super的公共方法，如

override the public method of super class, then call super's public method back like

示例。但编译给出了错误。我不知道为什么，怎么办？剂量java

example. but the compile gave error.I don't konw why, how could it do? Dose java have

类似反映方式以防止这种情况？

推荐答案

不，根据 public 的定义，您无法停止调用该方法（无论是派生类还是其他任何位置）。您当然可以阻止它被覆盖（从而确保用于调用它的语法不会使用 super ;-)它最终。

No, by definition of public you can't stop the method from being called (whether from a derived class or anywhere else). You can of course stop it from being overridden (and thereby ensure that the syntax used to call it won't use super;-) by making it final.
