java 实现将一个string保存到txt文档中

	private static String savefile = "E:\\test.txt";
private static void saveAsFileWriter(String content) {
 
	 FileWriter fwriter = null;
	 try {
	 fwriter = new FileWriter(savefile);
	 fwriter.write(content);
	 } catch (IOException ex) {
	 ex.printStackTrace();
	 } finally {
	 try {
	 fwriter.flush();
	 fwriter.close();
	 } catch (IOException ex) {
	 ex.printStackTrace();
	 }
	 }
	}
