标题: 【成都校区】字符动画
准备工作：1.通过KMPlayer视频播放器截图再通过读取图片取像素转字符播放
2.通过格式工厂将普通音频文件转为wav格式
代码部分：

      frame.setAlwaysOnTop(true);

                     }
                  } else if (a > 229214) {
                     are.setText("");

            }
            br.close();

            e.printStackTrace();
         }
      } catch (FileNotFoundException e) {
         e.printStackTrace();
      }
}
public static void main(String[] args) {
      Music.play();
   new BadApple();
   System.exit(0);
}

}

ImageForString.java:

import java.awt.image.BufferedImage;
import java.io.IOException;

public class ImageForString {
private final static char[] asc = { '*', '.', ' ', ' ' };
public static StringBuilder imageToAscii(BufferedImage image)throws IOException{
      StringBuilder strb=new StringBuilder();
      int width=image.getWidth();
      int height=image.getHeight();
      for(int i=0;i<height;i++){
         for(int j=0;j<width;j++){
            int rgb=image.getRGB(j,i);
            int R=(rgb&0xff0000)>>16;
            int G=(rgb&0x00ff00)>>8;
            int B=rgb&0x0000ff;
            int gray=R+G+B;
            int index=gray/255;
            strb.append(asc[index]);
         }
         strb.append("\n");
      }

      return strb;
}
}

Music.java:import java.applet.Applet;
import java.applet.AudioClip;
import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;

public class Music {
private static File musicFile;
private static  URL musicurl;
private static AudioClip ac;

public static void play(){
      musicFile = new File("badApple.wav");
      try {
         musicurl = musicFile.toURI().toURL();
      } catch (MalformedURLException e) {
         e.printStackTrace();
      }
      ac = Applet.newAudioClip(musicurl);
      ac.play();
}
}我是在CSDN上看到的有兴趣可以去学习了解一下效果：https://www.bilibili.com/video/av35989249/
