Command Returns Nothing

I am making a class plugin. Basically, I ran the command /class choose mage in-game and I also tried all the other classes and it didn't return any value. Not even a console error.

Main Class:

Code:

package com.boss86741.plugins.godlyclasses;
 
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.util.logging.Level;
 
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.configuration.file.YamlConfiguration;
import org.bukkit.plugin.java.JavaPlugin;
 
public class GodlyClasses extends JavaPlugin {
   
    // Config Stuffs Implementation
    private FileConfiguration customConfig = null;
    private File customConfigFile = null;
   
    public void reloadCustomConfig() {
        if (customConfigFile == null) {
        customConfigFile = new File(getDataFolder(), "config.yml");
        }
        customConfig = YamlConfiguration.loadConfiguration(customConfigFile);
   
        // Look for defaults in the jar
        InputStream defConfigStream = this.getResource("config.yml");
        if (defConfigStream != null) {
            YamlConfiguration defConfig = YamlConfiguration.loadConfiguration(defConfigStream);
            customConfig.setDefaults(defConfig);
        }
    }
   
    public FileConfiguration getCustomConfig() {
        if (customConfig == null) {
            this.reloadCustomConfig();
        }
        return customConfig;
    }
   
    public void saveCustomConfig() {
        if (customConfig == null || customConfigFile == null) {
        return;
        }
        try {
            getCustomConfig().save(customConfigFile);
        } catch (IOException ex) {
            this.getLogger().log(Level.SEVERE, "Could not save config to " + customConfigFile, ex);
        }
    }
   
    @Override
    public void onEnable() {
        getLogger().info("Say hi to the class plugin :)");
        GodlyCommands gc = new GodlyCommands(this);
        getCommand("class").setExecutor(gc);
        this.saveCustomConfig();
    }
   
    @Override
    public void onDisable() {
        getLogger().info("Bye, bye!");
    }
}

Command Class:

    private GodlyClasses plugin;
   
    public GodlyCommands(GodlyClasses plugin) {
        this.plugin = plugin;
    }
   
    String plName;
    // command code
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String string, String[] args) {
        if (cmd.getName().equalsIgnoreCase("class")) {
            if (args.length == 2) {
                if (args[1] == "choose") {
                    // choose the archer class

Arguments start at 0. So you should be checking if args[0] is choose and args[1] is whatever class (your args.length == 2 check is fine). Also, compare strings with .equalsIgnoreCase().
