Java 正在从文件加载字对，但未返回正确的字对

我得到一个错误：

public void testLoad()
  {
    assertTrue(wordPairDemo.save(fileName));    
    wordPairDemo.clear();                       
    assertTrue(wordPairDemo.load(fileName));
    assertTrue(wordPairDemo.size() == 3);
    assertEquals(wordPairDemo.lookup("hest"),"horse");
    assertEquals(wordPairDemo.lookup("hus"), "house");
    assertEquals(wordPairDemo.lookup("båd"),"boat");

  }

我在那里运行了其他测试，但唯一失败的是加载测试。我不太明白它为什么会失败，因为它正在返回值，但它没有正确地返回它们？有人能发现不允许它给它绿色的错误吗

编辑：

for循环的意义是什么？您将在其中返回

true

。所以你只需要做一次迭代，我明白你的意思了。我想这就是为什么它将我的加载方法重新调整为失败而不是错误。我需要在哪里放置true，以便在循环结束时提取它？如果此函数的目的是从给定文件创建所有字对，则应该将此返回语句放在while块之后。因此，现在我得到一个错误，错误4。我将用它更新原始问题。输入文件中的数据是什么？只有这个？马
