CREATE a file...

Does Java actually have support for file creation. I've not been having a good time with I/O when a file doesn't exist... :(

This might help you out. Be sure to import java.io.* or java.io.File into your app though. :p

Code:

---

public static void create(){
    // if directory already exists mkdir() will just return false and the directory
    // will not be overwritten.         
    try{                 
      File dir = new File("C:\\InitialDirectory");
      dir.mkdir();
        File f = new File("\\Justatextfile.txt");
        f.createNewFile();
          File dest = new File("C:\\InitialDirectory\\" + f.getName()); 
          f.renameTo(dest);
    }catch(IOException e){System.err.println(e);}
    }

---

Ok. Easy. :)
I just kept getting the impression that the
File f = new File("\\Justatextfile.txt");
line was raising a FileNotFound exception...

The file dosn't actually have to be there in order to create a new file object. Certian streams will throw a FileNotFoundException if the if a nonexistent file is passed in as an arguement. Some classes like RandomAccessFile will throw a FileNotFoundException when in 'r' mode and the file does not exist. But will create a file if in 'rw'.

i think this works:

Code:

---

import java.io.*;

PrintWriter file = new Printwriter ( new OutputSteamWriter ( new FileOutputStream ("asdf.txt")));

some of those class names amybe wrong but that close enuff 4 u 2 fig it out;)
