java文件流

File file = new File("E:/a.txt");
			if(file.isFile()&&file.exists()){
				FileInputStream fis = new FileInputStream(file);//变成文件输出流
				InputStreamReader reader = new InputStreamReader(fis);//一种管道
				BufferedReader br = new BufferedReader(reader);//转化成输出流
				String lineText = null;
				while((lineText = br.readLine())!=null){
					System.out.println(lineText);
				}
				fis.close();
				fis.close();
				reader.close();
				br.close();
			}
		}catch(Exception e){
