推荐答案

我很确定你不能在<$ c $中设置文本样式c> JTextField ，除了设置字体。我想你要么必须创建自己的子类来支持样式，要么创建一个 JTextPane 并将其设置为行为类似于 JTextField 。

I'm pretty sure you can't style text in a JTextField, beyond setting the font. I think you'll either have to create your own subclass which supports styling, or create a JTextPane and set it up to behave like a JTextField.
