Main args given as input to a File

[vamsi acharya]

hey guys , am having some trouble with the following code snippet

public static void main(String[] args ) {

for( int i=0;i<args.length;i++){
File f = new File(args[i]);
Thread t = new DigestThread(f);
t.start();

}

I don't understand this code , the File should be given its path why is it so that it is given arguments of main method as input ? And also i am currently using NetBeans IDE, how to pass arguments of main method ?? Thanks in advance !

You pretty much answered your own question. The arguments passed to main are the paths to the files!

Also, you should always indent your code for readability.

It slightly different, depending on the version you are using, so take these instructions with a grain of salt.

Instead of just choosing the "run as" --> "application" option, choose "run configurations...". With some versions of eclipse, it may be named something slightly different. This should open a popup. Look for an "arguments" tab -- this should allow you to enter the command line arguments to give to the application.

[EDIT: it looks like from your first post, that you are using NetBeans, and not eclipse -- sorry, I don't use NetBeans]

By "conventional" I take it you mean the command line. For that you need to run your application like java MyApp /path/to/file
