1.模拟QQ相册上传图片（上传指定文件夹下所有的图片）
    多线程上传（每个图片开辟一个子线程）

package ZUO;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

public class QQ {
    public static class xianc extends Thread{
        @Override
        public void run(){
            System.out.println(this.getName()+"-->上传图片");
            for (int i = 0; i < 5; i++) {
                System.out.println(this.getName()+ "t" +(i*20 + "%"));
                try {
                    xianc.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            System.out.println(this.getName()+"-->图片接收完毕");
        }
        private void xc() throws IOException {
            File file = new File("D:\cn.hp.demo\img\");
            String arr[]=file.list();
            for (int i = 0; i < arr.length; i++) {
                System.out.println(arr[i]);
                FileInputStream inputStream = new FileInputStream("D:\cn.hp.demo\img\"+arr[i]);
                FileOutputStream outputStream = new FileOutputStream("D:\img\"+arr[i]);
                int a =0;
                while ((a= inputStream.read())!=-1){
                    outputStream.write(a);

                }
                outputStream.close();
                inputStream.close();
            }
        }

    public static void main(String[] args) throws IOException {
       xianc a = new xianc();
       xianc b = new xianc();
       a.xc();
       a.start();
       b.start();

        }
    }
}
