求作业 编写一个图形界面的Java Application程序
java编写图形界面需要用到swing等组件，可以在eclipse中安装windowbuilder来开发窗体，自动生成窗体代码，然后自己再根据需要修改，如：
package mainFrame;
import java.awt.EventQueue;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JCheckBox;
import javax.swing.JFrame。
Java是一门面向对象编程语言，不仅吸收了C++语言的各种优点，还摒弃了C++里难以理解的多继承、指针等概念，因此Java语言具有功能强大和简单易用两个特征。Java语言作为静态面向对象编程语言的代表，极好地实现了面向对象理论，允许程序员以优雅的思维方式进行复杂的编程。
你好，按照你的要求代码如下，可以直接运行
import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.util.Arrays;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
public class SplitFrame extends JFrame {
private JTextArea textArea_1;
private JTextArea textArea;
public static void main(String args[]) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
SplitFrame frame = new SplitFrame();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
public SplitFrame() {
super();
getContentPane().setLayout(null);
setBounds(100, 100, 500, 383);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
final JButton button = new JButton();
button.addActionListener(new ActionListener() {
public void actionPerformed(final ActionEvent e) {
textArea.setText(null);
textArea_1.setText(null);
}
});
button.setText("清空");
button.setBounds(195, 310, 106, 28);
getContentPane().add(button);
final JScrollPane scrollPane = new JScrollPane();
scrollPane.setBounds(23, 46, 207, 240);
getContentPane().add(scrollPane);
textArea = new JTextArea();
scrollPane.setViewportView(textArea);
textArea.addKeyListener(new KeyAdapter() {
public void keyReleased(final KeyEvent e) {
String str = textArea.getText();
String[] a = str.split("[ ,
]");
Arrays.sort(a);
textArea_1.setText(null);
for (String s : a) {
if (!"".equals(s.trim())) {
textArea_1.append(s + "
");
}
}
}
});
final JScrollPane scrollPane_1 = new JScrollPane();
scrollPane_1.setBounds(252, 46, 207, 240);
getContentPane().add(scrollPane_1);
textArea_1 = new JTextArea();
scrollPane_1.setViewportView(textArea_1);
textArea_1.setEditable(false);
final JLabel label = new JLabel();
label.setText("在此输入");
label.setBounds(93, 22, 66, 18);
getContentPane().add(label);
final JLabel label_1 = new JLabel();
label_1.setText("即时排序");
label_1.setBounds(328, 22, 66, 18);
getContentPane().add(label_1);
}
}

基本满足了你的要求，其他功能很容易扩展，自己写写看吧。
