  • Use javac *.java for compiling all files inside one folder ! Commented Jul 27, 2014 at 9:31

  • SORRY no offense, but it is easy to mark a thread as duplicate but not as easy for everyone to find a thread similar to the question one wants to ask.I am looking for some command like set src=dir /s /b /o:n /ad to list the directory structure with sub directories then use javac %src%*.java to convert all .java files in the sub directories to .class file then delete the .java files Commented Jul 27, 2014 at 11:21
  • Why would you want to delete the .java files? How would you like to handle a compile error where no .class is generated and your .java has been deleted? Commented Jul 27, 2014 at 17:25

Reset to default

javac /yourdir/*.java /yourdir2/*.java

just add the directories from which you want to compile.

:For that I would have to type each and every folder and its sub-folders name which is not practical in case of multiple folders.@DavidPostill:I am not deleting the original .java files.Will make .class files of a copy of j.ava files
