22.08.29. 숙제 JFrame

1. 사용자가 사용자의 칸에 입력하고 버튼을 누르면 홀짝 게임이 실행되도록 하기.

package day04;

import java.awt.EventQueue;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.EmptyBorder;
import javax.swing.JTextField;
import javax.swing.JLabel;
import javax.swing.JButton;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

public class MySwing05 extends JFrame {

	private JPanel contentPane;
	private JTextField tf_mine;
	private JTextField tf_com;
	private JTextField tf_result;
	private JLabel lblNewLabel_2;
	private JButton btn;

	/**
	 * Launch the application.
	 */
	public static void main(String[] args) {
		EventQueue.invokeLater(new Runnable() {
			public void run() {
				try {
					MySwing05 frame = new MySwing05();
					frame.setVisible(true);
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		});
	}

	/**
	 * Create the frame.
	 */
	public MySwing05() {
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setBounds(100, 100, 450, 300);
		contentPane = new JPanel();
		contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
		setContentPane(contentPane);
		contentPane.setLayout(null);
		
		tf_mine = new JTextField();
		tf_mine.setBounds(276, 50, 116, 21);
		contentPane.add(tf_mine);
		tf_mine.setColumns(10);

		tf_com.setBounds(276, 95, 116, 21);
		contentPane.add(tf_com);
		
		tf_result = new JTextField();
		tf_result.setColumns(10);
		tf_result.setBounds(276, 144, 116, 21);
		contentPane.add(tf_result);
		
		JLabel lblNewLabel = new JLabel("나:");
		lblNewLabel.setBounds(84, 53, 57, 15);
		contentPane.add(lblNewLabel);
		
		JLabel lblNewLabel_1 = new JLabel("컴퓨터: ");
		lblNewLabel_1.setBounds(84, 98, 57, 15);
		contentPane.add(lblNewLabel_1);
		
		lblNewLabel_2 = new JLabel("결과: ");
		lblNewLabel_2.setBounds(84, 147, 57, 15);
		contentPane.add(lblNewLabel_2);
		
		btn = new JButton("홀짝게임");
		btn.addMouseListener(new MouseAdapter() {
			@Override
			public void mouseClicked(MouseEvent e) {
				resultGame();
			}
		});
		btn.setBounds(166, 199, 97, 23);
		contentPane.add(btn);
	}
	public void resultGame() {
		String user = tf_mine.getText();
		String com="";
		int rnd = (int)(Math.random()*2);
		if(rnd==0) {
			com="홀";
		}else {
			com="짝";
		}
		tf_com.setText(com);
		if(user.equals(com)) {
			tf_result.setText("승리");
		}else {
			tf_result.setText("패배");
		}
	}

}

2. 핸드폰처럼 번호를 누르면 TextField에 번호가 찍히고 Call버튼을 누르면 TextField의 수들을 지우기

늘 쉬운 것만 하고 살 순 없긴 한데 오후 수업은 토할 것 같다... 너무 빠르고 이해도 잘 안되고 흑흑 어케 이겨내냐
