Hung Hung: 第十一堂課

先去下載上禮拜的時鐘程式

Create a Timer object

進行修改
import javax.swing.Timer;
import java.awt.event.*;
import java.util.*;import java.awt.*;//加入要用的套件
import javax.swing.*;//加入要用的套件
public class TimerDemo extends JFrame implements ActionListener {
static JTextField tbx1=new JTextField(10);//加入文字方塊 Timer t = new Timer(1000,this);
TimerDemo() {
    t.start();
    }
public static void main(String args[]) {
    TimerDemo td = new TimerDemo();
GridLayout grid33= new GridLayout(3,3);//加入Layout，應該用什麼都可
JPanel p1 = new JPanel(grid33); //加入Panel
p1.add(tbx1);//在Panel中加入tbx1
td.add(p1);//在frame(td)中加入Panel
td.setLayout(grid33);//設定td的Layout
td.setVisible(true);//讓td看的見
td.setSize(450,450);//設定td大小
    // create a dummy frame to keep the JVM running
    // (for demonstation purpose)
    java.awt.Frame dummy = new java.awt.Frame();
    dummy.setVisible(true);
    }
public void actionPerformed(ActionEvent e) {
    if (e.getSource() == t) {
    // System.out.println
       // ("Being ticked " + Calendar.getInstance().getTime());
tbx1.setText("YA " + Calendar.getInstance().getTime());
//讀取文字方塊內的物件，前片加個字串，java會把後面的也當成字串顯示      }
    }
}

※extends JFrame 繼承
