将.class转换为.java [英] Convert .class to .java

问题描述

我有一些我需要转换为.java的.class文件，所以我做了：

I have some .class files that I need to convert to .java so I did:

javap -c ClassName.class

并且我一直有同样的错误

and all the time I have the same error

错误：找不到ClassName.class

ERROR:Could not find ClassName.class

你们有什么想法可能是原因？我做了man javap，据我所知，语法是正确的。如果有另一种方法将其转换为.java文件，我非常愿意尝试。非常感谢任何想法？

Do you guys have any idea of what might be the cause? I did man javap and as far as I know the syntax is correct. If there is another way to convert it to a .java file, I am more than willing to try. Any idea is greatly appreciated?

推荐答案

调用 javap 来读取字节码

javap 命令使用不带 .class 扩展名。尝试

Invoking javap to read the bytecode

The javap command takes class-names without the .class extension. Try

javap -c ClassName

将.class文件转换回.java文件

javap 但不会给出你在java语法中的方法的实现。它最多只能以JVM字节码格式提供给你。

Converting .class files back to .java files

javap will however not give you the implementations of the methods in java-syntax. It will at most give it to you in JVM bytecode format.

实际反编译（即反向执行 javac ）你将不得不使用适当的反编译器。例如，请参阅以下相关问题：

To actually decompile (i.e., do the reverse of javac) you will have to use proper decompiler. See for instance the following related question:
