Easiest way to edit/modify compiled class file
提问by Stackie Overflower
My main problem is that i have some class files from a game where i wan't to edit/modify parts of it
我的主要问题是我有一些来自游戏的类文件，我不想编辑/修改其中的某些部分
What would be the easiest way to achieve this ?
实现这一目标的最简单方法是什么？
Decompiling the whole code and recompiling is not an option unless you have some decompiler that doesn't cause errors in the source code, as i do not wish to spend time fixing them.
除非您有一些不会导致源代码错误的反编译器，否则反编译整个代码并重新编译不是一种选择，因为我不想花时间修复它们。
Best regards
最好的祝福

You can also use the Krakatau disassembler/assemblerI wrote. The disassembler turns a class file into a human readable (well readable if you understand bytecode anyway) format, which you can then edit and reassemble. This is useful if you want to view and edit the classfiles by hand, where writing a bunch of library calls and then compiling and running a program just to use ASM or BCEL is rather unwieldy.
您也可以使用我编写的Krakatau 反汇编器/汇编器。反汇编器将类文件转换为人类可读的（如果您理解字节码，则可读）格式，然后您可以对其进行编辑和重新组装。如果您想手动查看和编辑类文件，这很有用，在这种情况下，编写一堆库调用然后编译和运行程序只是为了使用 ASM 或 BCEL 是相当笨拙的。
Krakatau also has a decompiler specifically designed to handle obfuscated classes, so it may be able to produce valid source code even when no other decompiler can. Of course if the class is obfuscated, the generated source will probably still be unreadable.
Krakatau 还有一个专门设计用于处理混淆类的反编译器，因此即使其他反编译器无法生成有效的源代码，它也可以生成有效的源代码。当然，如果类被混淆，生成的源代码可能仍然无法读取。
