Basic Example of implementing a ping command using the CommandHandler

Main.java

package me.hopedev.testproj;

import me.hopedev.commandhandler.CommandBuilder;
import org.javacord.api.DiscordApi;
import org.javacord.api.DiscordApiBuilder;

public class Main {

    public static void main(String[] args) {

        // init javacord
        DiscordApi api = new DiscordApiBuilder().setToken("token").login().join();

        //CommandBuilder
        CommandBuilder builder = new CommandBuilder("!", api);

        // add !ping
        builder.addCommand("ping", new PingCommand(), "Gets the ping of the bot", "!ping");

        //build
        builder.build();
    }
}

PingCommand.java

package me.hopedev.testproj;

import me.hopedev.commandhandler.Command;
import me.hopedev.commandhandler.CommandData;
import me.hopedev.commandhandler.CommandExecutor;
import org.javacord.api.entity.message.Message;

import java.util.ArrayList;

public class PingCommand implements CommandExecutor {
    @Override
    public void execute(CommandData data, ArrayList<Command> commands) {
        long ping1, ping2, ms;

        ping1 = System.currentTimeMillis();
        Message message = data.getChannel().sendMessage("Ping..").join();
        ping2 = System.currentTimeMillis();
        ms = ping2-ping1;
        message.edit("Pong! `"+ms+"ms`");

    }
}
