how to create New file with specified file extension ?

hi,
here is the code that can able to create new file in my desired folder. Now what should i do if want to separate the file extension while using createNewFile() method ?

Code:

---

try{
File directory = new File("C:/Java/mydir");
directory.mkdirs();
 
File f = new File(directory, "info.txt");
f.createNewFile();
}

---

suppose, to create temp file, it has a method to separate the file extension.

Code:

---

File file = File .createTempFile( "info", ".txt", new File( "C:\\Java" ) );

---

have any method like this for createNewFile() method ??

Change your code to use String concatenation in that spot?

i.e.

Code:

---

File f = new File(directory, "info" + ".txt");

---

Edit: This is, afterall, essentially what createTempFile does (although it might create the name in a String var, then use that single String var, the principle is the same). It also uses "prefix" + "oneUpNumberNormally" + "suffix", but that is simply taking it one step further.

thanks a lot....

actually i was looking for this information that u made clear, really appreciate you
