Java-----图形设计(登陆界面)
思路：由于只是设计一个简单的登录界面，所以图形设计是需要设计按钮，标签，密码框，文本框。
代码如下：
package lianxi;import java.awt.GridLayout;import java.awt.Point;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.awt.event.WindowAdapter;import java.awt.event.WindowEvent;import javax.swing.AbstractButton;import javax.swing.JButton;import javax.swing.JFrame;import javax.swing.JLabel;import javax.swing.JOptionPane;import javax.swing.JPanel;import javax.swing.JPasswordField;import javax.swing.JTextField;public class lianxi1 {private static final Point center = null;private JFrame frame;private JLabel titleLabel,userLabel,mimaLabel;private JTextField nameJTextField;private JPasswordField passwordField;private JButton loginButton,zhuceButton;private JPanel titlePanel,userPanel,passwordPanel,buttonPanel;public AbstractButton nameTextField;public void shoW(){this.titleLabel=new JLabel("职业信息管理系统");this.userLabel=new JLabel("用户名");this.mimaLabel=new JLabel("密 码");this.nameJTextField=new JTextField(12);this.passwordField=new JPasswordField(12);this.loginButton=new JButton("登陆");this.zhuceButton=new JButton("注册");this.titlePanel=new JPanel();this.passwordPanel=new JPanel();this.buttonPanel=new JPanel();this.userPanel=new JPanel();this.titlePanel.add(this.titleLabel);this.userPanel.add(this.userLabel);this.userPanel.add(this.nameJTextField);this.passwordPanel.add(this.mimaLabel);this.passwordPanel.add(this.passwordField);this.buttonPanel.add(this.loginButton);this.buttonPanel.add(this.zhuceButton);frame=new JFrame("登陆窗口");frame.setLayout(new GridLayout(0,1));frame.add(this.titlePanel);frame.add(this.userPanel);frame.add(this.passwordPanel);frame.add(this.buttonPanel);frame.setSize(300,280);frame.setVisible(true);}public static void main(String[] args){lianxi1 text=new lianxi1();text.shoW();}}
