那是因为没有一个功能"可以改变JButton的文本颜色.您必须创建代码才能做到这一点.考虑使用:

That's because there is no one "function" that changes text color from a JButton. You have to create code to do it. Consider using:

• ActionListener响应按钮按下
在JTextField上
• setForeground(Color newColor)调用以设置其前景/文本颜色.
• 如何进行这些调用的细节都取决于您当前的代码，而我们尚未看到.
• 查看Swing教程，以后再做一些研究，并在提出类似问题时展示您的尝试.否则，我们将不知道您可能做错了什么.请查看帮助部分以及如何提出好的问题，以了解如何改善该问题并增加获得体面答案的几率.

• ActionListener to respond to button press
• setForeground(Color newColor) call on the JTextField to set its foreground/text color.
• The specifics on how to make these calls will all depend on your current code, something that we have not seen yet.
• Check the Swing tutorials and do a little more research in the future and show your attempt when asking similar questions. Else we'll have no idea what you may be doing wrong. Please look at the help section as well as how to ask good questions to find out how you can improve this question and increase your odds of getting decent answers.
