//
import javax.swing.*;

public class Form extends javax.swing.JFrame
{
JTextField username = new JTextField(15);
JPasswordField password = new JPasswordField(15);
JTextArea comments = new JTextArea(4, 15);

public void Form()

JPanel pane = new JPanel();

comments.setLineWrap(true);
comments.setWrapStyleWord(true);
pane.add(usernameLabel);
pane.add(username);
pane.add(passwordLabel);
pane.add(password);
pane.add(commentsLabel);
pane.add(comments);
setContentPane(pane);

show();
}

public static void main(String args[])
{
Form input = new Form();
}
}

[柯本]

public void Form()
构造函数不能定义返回值:
改为
public Form()
就可以了
