我今天在我们的代码中遇到了这个错误，花了一段时间才弄清楚。我发现它很有趣，因此决定分享它。这是问题的简化版本:

public class Test {

    static
    {
      text = "Hello";
    }

    public static String getTest() {
      return text + " World";
    }

    private static String text = null;
}

猜猜Test.getTest();返回什么，为什么？

最佳答案

它应该打印“null world”。静态初始化按照列出的顺序进行。如果将声明移到比静态块高的位置，则应显示“Hello World”。
