Java文件读写

// 文件读取

// 方法一

String path = "d:\a.txt";

BufferedReader  b= new BufferedReader(new FileReader(path));

String s;

while ((s = b.readLine()) != null) {

System.out.println(s);



} 

b.close();





//方法二

// String path = "d:\a.txt";

// BufferedInputStream i = new BufferedInputStream(new FileInputStream(path));

// int s1 = 0;

// byte[] b1= new byte[1024];

// while ((s1=i.read(b1)) != -1) {

// System.out.print(new String(b1,0,s1));;

//

// }

// i.close();
