java - RGB 创建时没有语句错误

Question

我有 39 个错误，但在同一件事上都是相同的错误 (kindve)，我不知道出了什么问题!错误都与这个类似:

Setup.java:31: error: ')' expected
                                                Selected[0] = (0,0,0);
                                                                ^
Setup.java:31: error: not a statement
                                                Selected[0] = (0,0,0);
                                                                 ^
Setup.java:31: error: ';' expected
                                                Selected[0] = (0,0,0);
                                                                  ^

这真是令人困惑，我不知道出了什么问题请帮忙!这是我的代码:

}

感谢任何帮助!谢谢!

我怀疑你想要这样的东西:

Selected[0] = new Color(0,0,0);

但您还应该阅读 this question ，因为您当前正在使用 == 比较字符串引用.老实说，你最好填充一个 Map<String, Color>而不是使用所有这些 if声明。

也没有明显的理由说明为什么要使用数组而不是简单的 Color 类型变量.
