textjframe.java

利用java语言构建一个文本的程序。这是最基本的程序练习例子！

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class TextJFrame extends JFrame
{
	JTextField text;
	JTextArea textArea;
	TextJFrame()
	{
		setSize(200,300);
		setLocation(200,300);
		text=new JTextField();
		textArea=new JTextArea();
		getContentPane().add(textArea);
		getContentPane().add(text,BorderLayout.NORTH);
		JButton exportToConsole=new JButton("export to console");
		exportToConsole.addActionListener(new ActionListener(){
			@Override public void actionPerformed(ActionEvent e){
			System.out.println(text.getText());
			text.setText("");
			textArea.append("onceabcdefghijklmnopqrstuvwxyz"+"\n");
			}
		});
		getContentPane().add(exportToConsole,BorderLayout.SOUTH);
		pack();
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setVisible(true);
	}
	
	public static void main(String[] args)
	{
		new TextJFrame();
	}

}
