# A Java Argument Parser

Parse command line arguments easily.

### Usage example

    import argparse.*;

    import argparse.arguments.*;

    public class Main {

        public static void main(String[] args) {

            ArgumentParser parser = new ArgumentParser("Test program", args);

    

            PositionalArgument arg1 = new PositionalArgument("file", "Enter the output filename");

            FlagInputArgument arg2 = new FlagInputArgument("--file", "-f", "The input file path");

            FlagArgument arg3 = new FlagArgument("--verbose", "-v", "Display verbose options");

            

            parser.addArgument(arg1);

            parser.addArgument(arg2);

            parser.addArgument(arg3);

    

            parser.parseArguments();

            

            // Prints true if arg1 is specified in args (PositionalArguments are required, this will always be true)

            System.out.println(arg1.isPassed());

            

            // Prints arg1's input

            System.out.println(arg1.getInput());

            

            // Prints true if arg2 is specified in args 

            System.out.println(arg2.isPassed());

            

            // Prints text arg2's input. Example: {"-f", "hello"} -> hello

            System.out.println(arg2.getInput());

            

            // Prints if arg3 is specified in args. Arg 3 is a FlagArgument and has no input. If getInput method is called, null is returned.

            System.out.println(arg3.isPassed());

        }

    }
