A very simple to use and extend JEditorKit that supports few languages. The main goal is to make it easy to have nice looking Java Swing Editors with support for Syntax Highlighting.
You first should think about using a common parser to create an AST (abstract syntax tree) from the sources. There are some tools around, first I find googling the internet was javaparser. It looks like this parser also records line numbers and columns, so the AST from javaparser can be a nice model for the editor.
Just process the tree, define colors for the AST node types and print it.
Might want to look at an existing editor (Notepad++ for example - http://notepad-plus.sourceforge.net/uk/site.htm) and see how user-defined syntax highlighting is done (oneo of the plugins to check - Gmod 10 Lua Syntax Highlighter). I'd wager that the Java (and other languages) are done similarly...

也许类似于
JSyntaxPane？Something like
JSyntaxPane, perhaps?RSyntaxTextArea 怎么样？ 它使用修改后的 BSD 许可证。
What about RSyntaxTextArea? It uses a modified BSD license.
您首先应该考虑使用通用解析器从源创建 AST（抽象语法树）。 有一些工具，首先我发现谷歌搜索互联网是 javaparser。 看起来这个解析器还记录了行号和列，因此 javaparser 中的 AST 对于编辑器来说是一个很好的模型。
只需处理树，定义 AST 节点类型的颜色并打印它。

可能想查看现有的编辑器（例如 Notepad++ - http://notepad-plus .sourceforge.net/uk/site.htm）并查看用户定义的语法突出显示是如何完成的（要检查的插件之一 - Gmod 10 Lua 语法突出显示）。 我敢打赌 Java（和其他语言）也是类似的......

您应该查看 Google 的 prettify.js。 其中有一些非常巧妙的技巧，您可能会对语法突出显示有更强大的感觉。
You should check Google's prettify.js out. Some pretty neat tricks in there, and you might get a more robust feel for syntax highlighting.
