从jar文件生成Javadoc和Java项目的方法

Question

I use Netbeans. I can make long java projects and then compile them to create a jar file which i can execute independently. But given a jar field, can someone tell how i can generate a java project from it and also its java-doc? Is there an available software that does it or can it be done form within IDE?

It's like saying i have written a C++ code to make an .exe file and wish to do something to extract the C++ source files and headers back from the .exe file. Can that be done?

Answer 1

Nop, you can't. I am assuming the documentation you are talking about is in the comments (javadocs): The comments stay in the source files and not in the artifacts.

Nonetheless, You can try reverse engineering for your jar: How to decompile a whole Jar file?

Answer 2

You can always try to decompile the code. By extracting the .class files from the jar then running the .class files through a decompiler.. However depending on how reputable the decompiler is, there is no guarantee that, that is exactly the code that was used. Also in terms of javadocs , if the decompiler is able to extract the javadoc comments I am sure you can then create a javadoc . However if it can not then you are out of luck besides making your own javadoc of the decompiled code.

Answer 3

actually i have another way to do it i think i couldn't found a way to do it by netbeans, but the best way that i founded was using Java Decompiler i has an option save all sources, create a java empty project in netbeans and then add the source there .
