Java JTextPanel文本突出显示？,java,text,jtextpane,Java,Text,Jtextpane,所以我从中得到了这个代码，我得到它来做我想做的事情，但是在我退格一种颜色的单词后，前面的所有单词也都是这种颜色 结果：这些单词是黄色的：yel，yw。这个词是红色的：rd。这些词是蓝色的：blu，be 结果：这些单词是黄色的：yel，yw。这个词是红色的：rd。这些词是蓝色的：blu，be 我把其中一个黄色的字退格了。现在我所有的话都是黄色的 代码： 封装测试； 导入java.awt.Color； 导入java.awt.Font； 导入javax.swing.JFrame； 导入javax.

所以我从中得到了这个代码，我得到它来做我想做的事情，但是在我退格一种颜色的单词后，前面的所有单词也都是这种颜色

结果：这些单词是黄色的：yel，yw。这个词是红色的：rd。这些词是蓝色的：blu，be

结果：这些单词是黄色的：yel，yw。这个词是红色的：rd。这些词是蓝色的：blu，be

我把其中一个黄色的字退格了。现在我所有的话都是黄色的
