BufferReader 缓存字符输入流

缓存字符输入流

可以以行为单位读取字符串

public static void main(String[] args) throws IOException {

FileInputStream fis = new FileInputStream("pw.txt");

InputStreamReader isr = new InputStreamReader(fis);

BufferedReader br = new BufferedReader(isr);

String str = null;

while((str=br.readLine())!=null){

System.out.println(str);

}

br.close();

}
