javaSE关于BufferedReader的笔记（2）

package IO;

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.InputStreamReader;

public class BufferedReaderTest02 {
    public static void main(String[] args) throws Exception{
        /*// 字节流
        FileInputStream in = new FileInputStream("Copy02.java");

        // 通过转换流转换
        InputStreamReader reader = new InputStreamReader(in);

        // 这个构造方法只能传字符流，不能传字节流
        BufferedReader br = new BufferedReader(reader);*/

        // 合并
        BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("Copy02.java")));

        String s = null;
        while ((s = br.readLine()) != null) {
            System.out.println(s);
        }

        br.close();
    }
}
