我的问题是在Guesser中我需要实例化GuessWhoGame类的主要方法，访问play方法，如果猜测是否正确则打印，并打印GuessWhoGame.class中的分数 在GuesserTest.java中我需要测试Guesser.play方法。 我该怎么办？我完全被难倒了
答案 0 :(得分：1)
初始化一个GuessWhoGame对象并调用它的播放方法。
非常基本：
@Test
public void testGuesser() {
GuessWhoGame guessWhoGame = new GuessWhoGame();
guessWhoGame.play();
// Do your test checks
}
答案 1 :(得分：0)
其中一些问题可以从各种java站点访问，但首先要让你开始：
要实例化另一个类，必须执行以下操作
GuessWhoGame gwg = new GuessWhoGame();
如果您想要其他构造函数，请执行以下操作
GuessWhoGame gwg = new GuessWhoGame(1);
所以在main方法中做这个部分，然后你可以从主要方法中调用GuessWhoGame的方法
还要玩
Guesser.play(gwg);
因为你是从静态主体那样做的，所以你不能使用＆＃34;这个＆＃34;但必须使用名称Guesser。
获得分数：
int s = gwg.score();
要打印行：
System.out.println("STUFF GOES HERE");
System.out.println("Score:"+s);
