ok, this is a basic questionfilename="/home/user/account.sav"; BufferedWriter writer=new BufferedWriter(new FileWriter(filename)); writer.write("whatever you want to write to the line"); writer.newLine(); //finally after u finish writer.close(); use your own file name... windows file name like "C:/myfolder/saveing.sav"; or relative file locations... and remember the call function must "throws IOException"

oh ... my godplease get a book and read the very basic part first before ask further more. String filename="xxx.txt"; String account="account.txt"; String whatever="xxx.txt"; except "String", no more keyword, you can change of coz!!!!

恩，不要太激动~~~我的意思是这样的 String account=MyInput.readInt(); 我要创建的文件是"accout".sav 就是说我想让account随着我的输入而变化 但是扩展名都是sav 这样也可以用上面的方法实现吗？ 谢谢你的耐心解答和关注

为什么不查API呢？API可是有用的咚咚啊。

I thinkHe has not found the usefulness of API, although he was told so. Hope he would find the API useful later (in CS1102?). :)

ok... see this String account="your directoty/your filename without .txt"; account=account+".txt"; myFile = new File(newaccount); and can you really "myfile=new File()"? i dont think so. unless you decleared your own class. note: pascal style is not working in Java
