// Copyright (c) 2018 FYIcenter.com
import org.apache.commons.cli.Options;
import org.apache.commons.cli.CommandLineParser;
import org.apache.commons.cli.CommandLine;
import org.apache.commons.cli.DefaultParser;
import org.apache.commons.cli.HelpFormatter;
import org.apache.commons.cli.UnrecognizedOptionException;
public class ArgumentOptionTest {
public static void main(String[] args) throws Exception {
// Define a long option: --help -help -h
Options options = new Options();
options.addOption("h", "help", false, "Print this help message");
// Define an option with argument: --input ..., -input ..., -i ...
options.addOption("i", "input", true, "Input string");
try {
// Parse options
CommandLineParser parser = new DefaultParser();
CommandLine cmd = parser.parse(options, args);
// Process options
if (cmd.hasOption("help")) {
help(options);
} else if (cmd.hasOption("input")) {
System.out.println("Hello "+cmd.getOptionValue("input"));
}
} catch (UnrecognizedOptionException e) {
System.out.println("Invalid options: "+e.getOption());
help(options);
