如何覆盖类的静态变量 [英] how do I override a static variable of a class

问题描述

我正在使用一个具有公共静态float变量的库，我想知道如何覆盖它
我想那不会发生？

I'm using a library it has a public static float variable I want to know how to override it I guess that's not going to happen?

//Settings.java
package org.jbox2d.common;

public class Settings {
    public static float velocityThreashold = 1.0f;
}

//MyClass.class
package org.jbox2d.common;

import com.otherlibrary
public class MyClass {

}

谢谢

推荐答案

示例中的velocityThreashold变量不是最终变量，也不是实例变量

The velocityThreashold variable in your example is not final, nor is it an instance variable and therefore cannot technically be overridden.

您可以做的就是将VelocityThreashold的值设置为您希望的任何值，因为它是公共的。

What you can do is set the value of velocityThreashold to any value you want since it's public.

我认为您要执行的操作如下：

I think what you're going to want to do is something like the following:

public static void main(String[] args) {
  org.jbox2d.common.Settings.velocityThreashold = 2.0f;

  //... the rest of your program
}
