缓冲流-复制图片

英语空隙。。Flush the toilet after you’re done. 上完厕所请冲水

package com.file.test;

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;

public class BufferedTest {
    public static void main(String[] args) throws Exception{
        BufferedInputStream bfin=new BufferedInputStream(new FileInputStream("F:/test/1.jpg"));
        BufferedOutputStream bfout=new BufferedOutputStream(new FileOutputStream("F:/test/1-copy.jpg"));

        byte[] area=new byte[2048];  //缓冲区大小
        int a=bfin.read(area);
        while(a!=-1){
            bfout.write(area,0,a);
            a=bfin.read(area);
        }

        bfout.flush();
        bfin.close();
        bfout.close();
        System.out.println("复制图片");
    }

}

结果：
