    Default Passing several files to another java program.

    Alright, so what I'm wondering is: What would be the best way to take a directory filled with files and pass them to another file? All of the files are ".java source code files"

    What I'm trying to do is take a directory filled with these files & write a process that passes each file in the list through JD-CLI & saves the decompiled source file to a destination directory.

    Decompiling this list of classes is taking forever because I have to do it one by one, thanks to CLI not granting us the ability I'm trying to write. Keep in mind I am starting this process from scratch! Thanks guys!

    Rather than use Java I would do this with something like a shell script, an Ant file, or some other platform that is typically used to run external applications on files.

    The File class has a method to return a list of files in a directory.
    The Runtime class has a method that will execute a command-line built in the program.

    Are those the capabilities you need?

    file is one of them I need; with runtime() would I be able to process the list of files obtained from the file function through jd-cli.jar?

    The Runtime class has a method that will execute a commandline. Do you have a command that can be executed from a commandline that will do what you want?
    Open a DOS window and execute a command to see if it does what you want. That command can then be executed in the Runtime class's method.

    through jd-cli.jar
    If the program you want to execute is a java program contained in a jar file and it can execute in the same JVM as the driver program, then you can call its main method directly without using the Runtime class's method.
    There would be a problem that would need special handling if the called program uses the System.exit() method.
