package shisanzhou;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.io.File;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.KeyStroke;

public class text {
	public static void main(String[] args) {
		JFrame frame=new JFrame("Welcome To MLDN");
		JTextArea text=new JTextArea();
		text.setEditable(true);
		frame.getContentPane().add(new JScrollPane(text));
		JMenu menuFile=new JMenu("文件");
		menuFile.setIcon(new ImageIcon("d:"+File.separator+"icons"+File.separator+"file.gif"));
		JMenuBar menuBar=new JMenuBar();
		JMenuItem newItem=new JMenuItem("新建",new ImageIcon("d:"+File.separator+"icons"+File.separator+"new.gif"));
		JMenuItem openItem=new JMenuItem("打开",new ImageIcon("d:"+File.separator+"icons"+File.separator+"open.gif"));
		JMenuItem closeItem=new JMenuItem("关闭",new ImageIcon("d:"+File.separator+"icons"+File.separator+"close.gif"));
		JMenuItem exitItem=new JMenuItem("退出",new ImageIcon("d:"+File.separator+"icons"+File.separator+"exit.gif"));
		newItem.setMnemonic('N');
		openItem.setMnemonic('O');
		closeItem.setMnemonic('C');
		exitItem.setMnemonic('E');
		newItem.setAccelerator(KeyStroke.getKeyStroke('N',java.awt.Event.CTRL_MASK));
		openItem.setAccelerator(KeyStroke.getKeyStroke('O',java.awt.Event.CTRL_MASK));
		closeItem.setAccelerator(KeyStroke.getKeyStroke('C',java.awt.Event.ALT_MASK));
		exitItem.setAccelerator(KeyStroke.getKeyStroke('E',java.awt.Event.ALT_MASK));
		menuFile.add(newItem);
		menuFile.add(openItem);
		menuFile.add(closeItem);
		menuFile.addSeparator();
		menuFile.add(exitItem);
		menuBar.add(menuFile);
		frame.addWindowListener(new WindowAdapter() {
			public void windowClosing(WindowEvent arg0) {
				System.exit(1);
			}});
		frame.setJMenuBar(menuBar);
		frame.setVisible(true);
		frame.setSize(300,180);
		frame.setLocation(300, 200);

四、个人总结

最近上课速度有些快，学习内容也比较多，还不能熟练的运用，需要多加的练习。慢慢来不能太心急
