文件读写

之前对用java语言实现从文件读数据 和将数据写入到文件一直很畏惧，现在实现了一个简单的写一行数据到文件和从文件中读数据出来

	public static void main(String[] args) throws IOException {
		File file=new File("F:/chatBotsProject/testReplace/fileinput/input.txt");
		BufferedWriter out=new BufferedWriter(new FileWriter(file));
		out.write("test writer some words to file");
		out.close();		
		
		BufferedReader reader=new BufferedReader(new FileReader(file));
		String line="";
		
		while(reader.ready())
			line=reader.readLine();
		
		reader.close();
		System.out.println(line);
		System.out.println("test success.");
	}
