缓冲字节输入流BufferedInputStream

1.在e盘下创建aaa.txt

1.代码

package d01_TestInput;/*

 */

import java.io.BufferedInputStream;
import java.io.FileInputStream;

public class TestBufferedInputStream {
    public static void main(String[] args) throws Exception {
        FileInputStream fis = new FileInputStream("e:\\aaa.txt");
        BufferedInputStream bis = new BufferedInputStream(fis);

        /*//2.单个读取
        int data = 0;
        while((data=bis.read())!=-1){
            System.out.println((char)data);
        }*/

        //2.1多个字节读取
        byte[] buf = new byte[1024];
        int len =0;
        while ((len=bis.read(buf))!=-1){
            System.out.println(new String(buf,0,len));
        }


        //3.关闭缓冲流会自动关闭节点流
        bis.close();

    }
}

2.输出结果
