铂西学习日记---打印流

* 打印流--就是为了方便进行输出,打印流分为两类，分别是
* 1.字符打印流 --- printWriter
* 2.字节打印流 --- printStream

import java.io.*;

public class demo_io5_print {
    public static void main(String[] args) {
//        bytePrint();

            //字节输出缓冲流--加缓存提高效率
            BufferedOutputStream bos = new BufferedOutputStream(out);

            PrintStream ps = new PrintStream(bos);
            ps.println("你好啊");
            //依然会关闭以上的流
