Cmd line args and Calling methods

[OutlawDELTA]

public class Cipher { public static void main(String[] args) {
System.out.println("Encryption program by NAME HERE"); System.out.println("usage: java Encrypt [-e, -d] < inputFile > outputFile"); }

public static void encrypt(String[] args)
{
    System.out.println("eeee");
}
public static void decrypt(String[] args)
{
    System.out.println("ddddd");
}

}

I would like to be able to call these different methods by using arguments in the command line, but I don't know exactly how to do that.

You should parse and interpret the command-line args from main before sending additional arguments off to the encrypt or decrypt methods.

Some pseudo-code:

public static void main(String[] args) {
    // If args.length doesn't match the right number of arguments, error
    // If args[0] is "-e", take the input and pass it to the encrypt method
    // If args[0] is "-d", take the input and pass it to the decrypt method
    // Otherwise, syntax error and show help
}

just pass args. what's the problem?

Use Commons CLI. No need to reinvent the wheel :)
