在Java中绘制其他像素

Question

我试图在框架上绘制每个像素，但是我无法算出如何绘制下一个像素，它仅显示一个像素绘制，PLZ帮助。我不知道如何实现此目标会编辑此代码，以便它在相邻坐标中绘制像素。

import java.lang.*;
import java.util.*;
import java.util.List;
import java.io.*;
import java.awt.*;
import java.awt.event.*;
import java.awt.geom.*;
   public class MyDrawPixel extends Frame {
      public Point mypoint = new Point();      
      public static void drawPixel(Graphics g, int x, int y, int size, Paint color)
     {
         Graphics2D ga = (Graphics2D)g;
         Shape circle = new Ellipse2D.Float(x, y, size, size);   
         ga.setPaint(color);
         ga.draw(circle);
         ga.setPaint(color);
         ga.fill(circle);
     }
     public void paint(Graphics g) {
        Graphics2D ga = (Graphics2D)g;
        drawPixel(g, mypoint.x, mypoint.y, 1, Color.black);
     }

  public static void main(String args[])
  {    
      MyDrawPixel frame = new MyDrawPixel();    
      frame.mypoint.x = 43;
      frame.mypoint.y = 43;
      MyDrawPixel frame1 = new MyDrawPixel();    
      frame1.mypoint.x = 44;
      frame1.mypoint.y = 44;
      MyDrawPixel frame2 = new MyDrawPixel();    
      frame2.mypoint.x = 45;
      frame2.mypoint.y = 45;
      MyDrawPixel frame3 = new MyDrawPixel();    
      frame3.mypoint.x = 46;
      frame3.mypoint.y = 46;
      MyDrawPixel frame4 = new MyDrawPixel();    
      frame4.mypoint.x = 47;
      frame4.mypoint.y = 47;
      frame.addWindowListener(
      new WindowAdapter()
      {
          public void windowClosing(WindowEvent we)
         {
            System.exit(0);
         }
      }
      );
       frame.setSize(400, 400);
      frame.setVisible(true);
   }
}

您正在创建5帧，并且仅显示一个。您需要做的是创建1帧并正确显示。

您可以使用 repaint()刷新屏幕，然后如果要移动单个点，只需更改重新粉刷之间的属性。

甚至更好，找到有关自定义绘画的适当教程，您的代码非常可怕。
