创建2个窗体，分别实现以下内容：1.绘制文本，通过设置Font类和颜色，实现效果如下：要求：在一个窗体中重写pait()函数，用drawSting()方式实现。2.涂鸦板是一个具有趣味性的小程序，它的实现原理是通过鼠标事件，控制鼠标移动结合画图功能实现。鼠标拖拽才开始绘制，松开鼠标则停止绘制。请用Java图形界面的知识，编写以上软件。

好的，我会根据你的要求为你解答。以下是实现代码：

1. 绘制文本窗体：

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class TextFrame extends JPanel {
    
    public void paint(Graphics g) {
        super.paint(g);
        Font font = new Font("Arial", Font.BOLD, 30);
        g.setFont(font);
        g.setColor(Color.BLUE);
        g.drawString("Hello World!", 50, 50);
    }
    
    public static void main(String[] args) {
        JFrame frame = new JFrame("Text Frame");
        frame.add(new TextFrame());
        frame.setSize(300, 200);
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
}

2. 涂鸦板窗体：

import java.awt.Color;
import java.awt.Graphics;
import java.awt.Point;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class DoodleBoard extends JPanel {
    
    private Point startPoint, endPoint;
    
    public DoodleBoard() {
        addMouseListener(new MouseAdapter() {
            public void mousePressed(MouseEvent e) {
                startPoint = e.getPoint();
            }
            
            public void mouseReleased(MouseEvent e) {
                endPoint = null;
            }
        });
        
        addMouseMotionListener(new MouseAdapter() {
            public void mouseDragged(MouseEvent e) {
                endPoint = e.getPoint();
                repaint();
            }
        });
    }
    
    public void paint(Graphics g) {
        super.paint(g);
        if (startPoint != null && endPoint != null) {
            g.setColor(Color.RED);
            g.drawLine(startPoint.x, startPoint.y, endPoint.x, endPoint.y);
        }
    }
    
    public static void main(String[] args) {
        JFrame frame = new JFrame("Doodle Board");
        frame.add(new DoodleBoard());
        frame.setSize(400, 400);
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
}

希望能对你有所帮助！
