Editing java class file - john1992 - Jun 4, 2018

I was trying to patch some class file inside a jar file. I used Krakatau to disassemble & reassemble the class file & after editing the files, the size of those files is changed though the content is same. Can anyone please tell me why this happen? I need the patch file without changing the file size. So curious how can I do that. File link - www7. zippyshare.com/v/diNNVsTz/file.html

you cant unless you change string with same string size.
if you add code you add bytes to compile.

I have changed the code with same bytes, one of the three files was retained the same size along with the same code while disassembling it with "javap -c" but other two shows different values in disassembling. Please take a look at the files in the link.
