如何在Java Swing Application Framework中处理命令行参数

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class CommandLineParser {

    public static void main(String[] args) {
        String commandLine = "java -jar myapp.jar arg1 arg2";
        CommandLineParser parser = new CommandLineParser();
        String[] parameters = parser.parse(commandLine);

        System.out.println("Parameters: " + parameters.toString());
    }

    public String[] parse(String commandLine) {
        try {
            ProcessBuilder builder = new ProcessBuilder(commandLine.split(" "));
            Process process = builder.start();
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            int index = 0;
            while ((line = reader.readLine()) != null) {
                System.out.println("Line " + index + ": " + line);
                index++;
            }
            reader.close();
            return builder.getParameters();
        } catch (IOException e) {
            e.printStackTrace();
            return null;
        }
    }
}
