要求如题

代码如下：

SmileFace01:

import java.awt.Color;
import java.awt.Graphics;import javax.swing.JPanel;public class SmileFace01 extends JPanel {@Overrideprotected void paintComponent(Graphics g) {super.paintComponent(g);int width = getWidth() / 2;int height = getHeight() / 2;// 绘制脸部g.setColor(Color.YELLOW);g.fillOval(100, 50, width, height);// 绘制眼睛g.setColor(Color.BLACK);int eyeSize = width / 8;int eyeY = height / 4 + 50;g.fillOval(width / 4 - eyeSize / 2 + 100, eyeY, eyeSize, eyeSize);g.fillOval(width * 3 / 4 - eyeSize / 2 + 100, eyeY, eyeSize, eyeSize);// 绘制嘴巴g.drawArc(135, 105, 120, 100, 0, -180);}
}

SmileJFrame01:

import javax.swing.JFrame;
import javax.swing.JLabel;import java.awt.Font;public class SmileJFrame01 extends JFrame {public SmileJFrame01() {JFrame jFrame = new JFrame("Smile");jFrame.setSize(400, 400);jFrame.setLocation(400, 300);jFrame.setDefaultCloseOperation(3);// 添加文字JLabel jLabel = new JLabel("Smiling...");jLabel.setBounds(145, 260, 150, 20);jLabel.setFont(new Font("宋体", Font.BOLD, 20));jFrame.add(jLabel);SmileFace01 panel = new SmileFace01();jFrame.add(panel);jFrame.setVisible(true);}
}

SmileFace02:

import java.awt.Color;
import java.awt.Graphics;import javax.swing.JPanel;public class SmileFace02 extends JPanel {@Overrideprotected void paintComponent(Graphics g) {super.paintComponent(g);int width = getWidth() / 2;int height = getHeight() / 2;// 绘制脸部g.setColor(Color.YELLOW);g.fillOval(100, 50, width, height);// 绘制眼睛g.setColor(Color.BLACK);int eyeSize = width / 8;int eyeY = height / 4 + 50;g.fillOval(width / 4 - eyeSize / 2 + 100, eyeY, eyeSize, eyeSize);g.fillOval(width * 3 / 4 - eyeSize / 2 + 100, eyeY, eyeSize, eyeSize);// 绘制嘴巴g.fillOval(135, 108, 120, 100);g.setColor(Color.yellow);g.fillOval(135, 107, 120, 90);}
}

SmileJFrame02:

import javax.swing.JFrame;
import javax.swing.JLabel;import java.awt.Font;public class SmileJFrame02 extends JFrame {public SmileJFrame02() {JFrame jFrame = new JFrame("Smile");jFrame.setSize(400, 400);jFrame.setLocation(800, 300);jFrame.setDefaultCloseOperation(3);// 添加文字JLabel jLabel = new JLabel("Smiling...");jLabel.setBounds(145, 260, 150, 20);jLabel.setFont(new Font("宋体", Font.BOLD, 20));jFrame.add(jLabel);SmileFace02 panel = new SmileFace02();jFrame.add(panel);jFrame.setVisible(true);}
}

Test:

public class Test {public static void main(String[] args) {SmileJFrame01 frame01 = new SmileJFrame01();SmileJFrame02 frame02 = new SmileJFrame02();}
}
