课程总结

AWT工具类有三种：
``` （1）组件：Component； （2）容器：Container； （3）布局管理器：LayoutManager； ```
常用的组件
``` 1.容器组件

JFrame 窗体类 最顶级的容器（默认布局为边框布局，不能自己互相添加）

JPanel 面板类 最灵活的容器（可以自己互相添加）

2.元素组件

JLabel 标签类

JTextField 文本输入框类（可以设置框内字符、输入框长度）

JPasswordField 密码输入框类（框内字符会被特定字符代替）

JCheckBox 复选框类

JComboBox 下拉框类

JButton 按钮类

容器和组件都是swing包下的类。javax.swing.JFrame

###图片设置代码：

package 第十一周实验;

import java.awt.Color;
import java.io.File;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPasswordField;
import javax.swing.JTextField;

public class test {
public static void main(String agrs[]) {
JFrame gg = new JFrame("QQ");
String photo = "d:" + File.separator + "6-1611131I42L00.gif";
Icon icon = new ImageIcon(photo);
JLabel pp = null;
pp = new JLabel(icon, JLabel.CENTER);
pp.setBackground(Color.YELLOW);
pp.setForeground(Color.RED);

	gg.add(pp);

	gg.setSize(400, 300);

	gg.setLocation(300, 100);

	gg.setVisible(true);

}

}

###制作登入界面：

package 第十一周实验;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPasswordField;
import javax.swing.JTextField;

public class wenbenk {
public static void main(String agrs[]) {
JFrame gg = new JFrame("QQ");
JLabel aa = new JLabel("账号名称:");
JLabel ss = new JLabel("账号密码:");
JTextField ff = new JTextField();
JPasswordField dd = new JPasswordField();
aa.setBounds(100, 100, 80, 20);
ss.setBounds(100, 140, 80, 20);
ff.setBounds(190, 100, 100, 20);
dd.setBounds(190, 140, 100, 20);
gg.setLayout(null);
gg.add(aa);
gg.add(ss);
gg.add(ff);
gg.add(dd);
gg.setSize(400, 300);

	gg.setLocation(300, 100);

	gg.setVisible(true);

}

}
