在GuesserTest.java我有

import static org.junit.Assert.*; 

import org.junit.Test; 


public class GuesserTest { 

    @Test 
    public void testGuesser() { 

    } 
    @Test 
    public void testMain() { 
     Guesser.main(new String[0]); 
    } 

    @Test 
    public void testConstructor() { 
     new Guesser(); 
    } 
}

我的问题是在Guesser中我需要实例化GuessWhoGame类，访问play方法，如果猜测正确与否，则打印并打印GuessWhoGame.class 和GuesserTest中的分数。我需要测试Guesser.play方法。我该怎么做？我完全难住了

我知道我并不想读的代码墙。提供公共调用方法，您可以轻松完成此操作。 – duffymo 2014-09-29 19:02:19

请不要只是把你的作业倒在这里，并要求我们为你做。你在问什么是基本的Java，如果你不知道如何开始，那么你需要回去学习你的课程材料。如果您遇到困难，请提出问题并发布您尝试的代码 - 您的_own_代码，而不是“pritchey”编写的代码。 – ajb 2014-09-29 19:06:27

Guesser是我自己的代码，我只是不知道如何访问不在同一个文件中的方法。我全面搜索了它。通过查看你的代码，其他代码被给予我 – Joe 2014-09-29 19:20:38

有些问题可以从不同的Java站点进行访问，但让你先开始第一件事：

实例化另一个类必须做到以下

GuessWhoGame gwg = new GuessWhoGame();

如果您需要其他构造函数，请执行以下操作

GuessWhoGame gwg = new GuessWhoGame(1);

所以做这一部分的主要方法，那么你可以调用，在主

同样在GuessWhoGame的方法来发挥

Guesser.play(gwg);

因为你从你不能用静态的主这样做“this”但是必须使用名字Guesser来代替。

要获得得分：

int s = gwg.score();

执行打印线：

System.out.println("STUFF GOES HERE"); 
System.out.println("Score:"+s);

@Joe看起来你不得不说玩（gwg）。观察Guesser中的播放方法。通过查看代码，没有经常播放（），只有一个播放（GuessWhoGame） – Rika 2014-09-29 19:14:35

假设我想访问GuessWhoGame中的猜测方法和Score方法猜猜谁是游戏并打印结果，我该怎么做？我需要存储然后执行它？比如int score = score（gwg）; ？ – Joe 2014-09-29 19:19:22

@Joe，好吧，首先我想你不了解发生了什么。所以让我们先看看播放方法。去Guesser类并寻找play方法并查看它的参数（或括号中的内容），它有什么内容？所以现在进入GuessWhoGame并寻找评分方法，参数（或括号中的内容）对它们有什么影响？ – Rika 2014-09-29 19:42:19

初始化一个GuessWhoGame对象并将其称为play方法。

非常基本：
