		// TODO Auto-generated method stub
		//例如 对c:/a.txt进行读取
		String string;
		try {
			FileInputStream fileInputStream=new FileInputStream("c://a.txt");
			BufferedReader bufferedReader=new BufferedReader(new InputStreamReader(fileInputStream));
			string=bufferedReader.readLine();
			System.out.println(string);
			while (string!=null) {
				string=bufferedReader.readLine();
				System.out.println(string);
