如何将字符串写入到记事本中，而不覆盖原来的内容
public static void main(String[] args) {Date date=new Date();SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");SimpleDateFormat sdf2=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");String date2=sdf2.format(date);String fileName=sdf.format(date);String path="E:\\log\"+fileName+".txt";File file=new File(path);if(!file.exists()){try {FileOutputStream out=new FileOutputStream(file,true);out.write("hao".getBytes());out.write(",".getBytes());out.write("192.168.1.106,".getBytes());out.write(date2.getBytes());out.write("\n".getBytes());out.close();} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}else{try {RandomAccessFile raf=new RandomAccessFile(path,"rw");raf.seek(raf.length());raf.write("lin,192.168.1.200,".getBytes());raf.write(date2.getBytes());raf.write("\n".getBytes());raf.close();} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}}?
以上代码是每天根据年月日生产一个记事本文件，用年月日来做为记事本的名字。如果根据当天的年月日命名的记事本不存在，那么就自动创建记事本。否则的话。就向该记事本中写入你想写入的信息。
