具體實現流程與上一篇部落格（上一篇部落格點選這裡）

程式碼如下：

package course;

import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import dao.CourseManager;;;
public class Cadd extends Dialog implements ActionListener{
	private Panel p1,p2,p3;
	private Label lab1,lab2,lab3,lab4;
	private TextField t1,t2,t3,t4;
	private Button btn1,btn2;
	public Cadd(Frame f,String title,boolean mo) {
		super(f, title, mo);
		p1.setLayout(new GridLayout(4,1));
		lab1=new Label("課程號");
		lab2=new Label("課程名稱");
		lab3=new Label("課程型別");
		lab4=new Label("課程內容");
		
		p1.add(lab1);
		p1.add(lab2);
		p1.add(lab3);
		p1.add(lab4);
		
		this.add(p1, BorderLayout.WEST);
		p2=new Panel();

		p3=new Panel();
		btn1=new Button("確定");
		btn1=new Button("取消");
		btn1.addActionListener(this);

	}

	@Override
