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());
    }
