推荐答案

你提到的类是J2ME的一部分，所以如果你想使用依赖于一类具有相同名称的非J2ME类（即J2SE）（即J2SE等价类），你有问题。

The class you mention is part of J2ME, so If you want to use non-J2ME classes (i.e. J2SE) that rely on a class of the same name (i.e. the J2SE equivalent class), you have a problem.

我不知道它是值得的，但如果你能识别的全套所需的SE类，并使用不同的包名（从源代码编译它们像 my.java.io ）后你可以在端口你需要的功能额外位，避免冲突。你会带来刚需到项目的J2SE code的本地副本。

I'm not sure it's worth it, but if you can identify the full set of SE classes needed, and compile them from source using a different package name (something like my.java.io for example) you could port over the extra bits of functionality you need, and avoid the clash. You would be bringing a local clone of just the J2SE code needed into your project.
