title: Recompile to *.Jar After decompile and fix the code?
body: <p>I have a myfile.jar file.
  I use jd-gui to decompile all *.class in a folder in myfile.jar. I get many *.java files in many folders</p>
  
  <p>After fixing some code in some *.java, now I would like to recompile all *.java back to *.class, and pack the whole folder back to myfile.jar.</p>
  
  <p>How do I do this?</p>
  
  <p>(This is my first time playing with java code.)</p>
