코드가 굉장히 길어요;;;

메인클

package UtilitiesStudio;

public class Main {
    public static final int SCREEN_SIZE = 1000;
    public static final int SCREEN_WIDTH = 500; 
    public static final String GUI_TITLE = "Ultimate Studio 2021"; 

    public static void main(String[] args) {
        new UtilitiesStudioGUI();
    }
}

new 에 붙어있는 UtilitiesStudioGUI 클래스

package UtilitiesStudio;

import java.awt.FlowLayout;
import java.awt.BorderLayout;

import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JComboBox;
import javax.swing.JPanel;


public class UtilitiesStudioGUI extends JFrame {
    UtilitiesStudioGUI() {
        setSize(Main.SCREEN_SIZE, Main.SCREEN_WIDTH);
        setTitle(Main.GUI_TITLE);
        setVisible(true);
        setLocation(0, 0);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        CombatMenu();

    }

    void CombatMenu() { 
        String[] Combat = { "AntiBot - Hypixel" , "AntiBot - Adavanced" , "AntiBot - NCP" , "AntiBot - Spartran" , "AutoPotion" , "AutoGoldenApple" , "Kill Aura - Vanilla" , "Kill Aura - NCP" , "Kill Aura - AAC" , "Kill Aura - Hypixel" , "Infinite Aura" , "Team" , "Regen" , "Auto Armor" , "AutoClicker" , "AimBot" , "AimAssist"};

        JPanel panel = new JPanel(new FlowLayout(FlowLayout.CENTER, 10, 10));

        JComboBox<String> CombatMenu = new JComboBox<>(Combat);

        panel.add(CombatMenu);

        add(panel, BorderLayout.CENTER);
    }

    void MoveMenu() {
        String[] Move = { "Air Jump" , "Buffer Speed" , "Better Jump" , ""};

        JPanel panel = new JPanel(new FlowLayout(FlowLayout.CENTER, 10, 10));

        JComboBox<String> MoveMenu = new JComboBox<>(Move);

        panel.add(MoveMenu);

        add(panel, BorderLayout.CENTER);
    }
} 

괸히 만들었나봅니다.

자바 스윙 GUI 에 핵 목록을 보여주는(작동은 안해요) 프로그램을 만들고있었는데 어디가 문제인지 작동을 안하더라고요 ㅋㅋㅋㅋㅋㅋ

망했네요.

나중에 다시 시도해봐야죠. 뭐.
