在GuesserTest.java我有

import static org.junit.Assert.*;

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

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

我的問題是在Guesser中我需要實例化GuessWhoGame類，訪問play方法，如果猜測正確與否，則打印並打印GuessWhoGame.class 和GuesserTest中的分數。我需要測試Guesser.play方法。我該怎麼做？我完全難住了

我知道我並不想讀的代碼牆。提供公共調用方法，您可以輕鬆完成此操作。 – duffymo 2014-09-29 19:02:19

請不要只是把你的作業倒在這裏，並要求我們爲你做。你在問什麼是基本的Java，如果你不知道如何開始，那麼你需要回去學習你的課程材料。如果您遇到困難，請提出問題併發布您嘗試的代碼 - 您的_own_代碼，而不是「pritchey」編寫的代碼。 – ajb 2014-09-29 19:06:27

Guesser是我自己的代碼，我只是不知道如何訪問不在同一個文件中的方法。我全面搜索了它。通過查看你的代碼，其他代碼被給予我 – Joe 2014-09-29 19:20:38

有些問題可以從不同的Java站點進行訪問，但讓你先開始第一件事：

實例化另一個類必須做到以下

GuessWhoGame gwg = new GuessWhoGame();

如果您需要其他構造函數，請執行以下操作

GuessWhoGame gwg = new GuessWhoGame(1);

所以做這一部分的主要方法，那麼你可以調用，在主

同樣在GuessWhoGame的方法來發揮

Guesser.play(gwg);

因爲你從你不能用靜態的主這樣做「this」但是必須使用名字Guesser來代替。

要獲得得分：

int s = gwg.score();

執行打印線：

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

@Joe看起來你不得不說玩（gwg）。觀察Guesser中的播放方法。通過查看代碼，沒有經常播放（），只有一個播放（GuessWhoGame） – Rika 2014-09-29 19:14:35

假設我想訪問GuessWhoGame中的猜測方法和Score方法猜猜誰是遊戲並打印結果，我該怎麼做？我需要存儲然後執行它？比如int score = score（gwg）; ？ – Joe 2014-09-29 19:19:22

@Joe，好吧，首先我想你不瞭解發生了什麼。所以讓我們先看看播放方法。去Guesser類並尋找play方法並查看它的參數（或括號中的內容），它有什麼內容？所以現在進入GuessWhoGame並尋找評分方法，參數（或括號中的內容）對它們有什麼影響？ – Rika 2014-09-29 19:42:19

初始化一個GuessWhoGame對象並將其稱爲play方法。

非常基本：
