[Java] 랜덤 점심 메뉴 고르기 프로그램

이런식으로 돌아간다 ㅎㅎ;
처음 실행하면 빈공간이고 클릭하면 랜덤으로 마구 돌고 다시 클릭하면 메뉴가 선택되는 방식이다

소스는 아래와 같다
아주 간단하다

package Bab;

import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.util.ArrayList;

import javax.swing.*;

public class Bab extends JFrame implements ActionListener {
	private JTextArea textArea;
	private JButton button;
	private JPanel textPanel, buttonPanel;
	private ArrayList bobList = new ArrayList();

	private boolean startCheck = false;

	private int count = 0;
	
	public static void main(String[] args) {
		Bab bob = new Bab();
		bob.dataSet();
		bob.createWindow();
	}

	private void dataSet() {
		try {
			FileReader fr = new FileReader("밥.dat");
			BufferedReader br = new BufferedReader(fr);
			String line = "";
			while((line = br.readLine()) != null) {
				bobList.add(line);
			}
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException ioe) {
			ioe.printStackTrace();
		}
	}
	
	private void createWindow() {
		Container container = this.getContentPane();
		
		textPanel = new JPanel();
		textArea = new JTextArea();
		textArea.setFont(new Font("", Font.BOLD, 100));
		textArea.setForeground(Color.BLUE);
		textArea.setBackground(Color.WHITE);
		textPanel.add(textArea);

		buttonPanel = new JPanel();
		button = new JButton("Click");
		button.addActionListener(this);
		buttonPanel.add(button);
		
		container.add(textPanel, BorderLayout.CENTER);
		container.add(buttonPanel, BorderLayout.SOUTH);
		
		this.setBounds(300, 300, 300, 200);
		this.setResizable(false);
		this.setVisible(true);
		this.setTitle("밥");
		this.setDefaultCloseOperation(EXIT_ON_CLOSE);
		button.requestFocus();
	}
	
	private boolean toggle() {
		return startCheck = !startCheck;
	}

	@Override
	public void actionPerformed(ActionEvent e) {
		if(toggle()) {
			Loop loop = new Loop();
			loop.start();
		}
		button.requestFocus();
	}

	class Loop extends Thread {
		@Override
		public void run() {
			while(startCheck == true) {
				textArea.setText(bobList.get(count));
				if(++count == bobList.size()) {
					count = 0;
				}
				try {
					Loop.sleep(18);
				} catch (InterruptedException e) {
					e.printStackTrace();
				}
			}
		}
	}
}

"밥.dat"라는 데이터 파일이 있어야 돌아간다
