怎样用java编写图形界面的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；import javax.swing.JLabel；import javax.swing.JPanel；import javax.swing.JPasswordField；import javax.swing.JTextField；import javax.swing.SwingConstants；import javax.swing.UIManager；import javax.swing.UnsupportedLookAndFeelException；import javax.swing.border.EmptyBorder；public class Mian_login extends JFrame {private JPanel contentPane；private JTextField text_LoginName；private JPasswordField Login_password；Launch the application.public static void main(String[]args){EventQueue.invokeLater(new Runnable(){Overridepublic void run(){try {Mian_login frame=new Mian_login()；frame.setVisible(true)；} catch(Exception e){e。.
