Java核心编程--缓冲流BufferedReader嵌套输入流FileReader

    public static void main(String[] args) throws Exception{
        //缓冲流

//        BufferedInputStream bis=new BufferedInputStream(new FileInputStream(new File("a.txt")));//也可以写文件


        BufferedReader br =new BufferedReader(new FileReader(new File("src/Basic_IO/a.txt")));
//        System.out.println(br.readLine());//是读取文本文件一行最好用的方法
        String str="";
        while ((str=br.readLine())!=null){//读取内容最好的方式
            System.out.println(str);
        }
        br.close();



        BufferedReader bs=new BufferedReader(new FileReader(new File("src/Basic_IO/a.txt")));
        String st="";
        while ((st=bs.readLine())!=null){
            System.out.println(st);
        }
        bs.close();
    }
