Dos Variable in Java

Question

Hi,
I am trying to write some Java code which will load a file stored in the User Profile file (ie. D:\Document and Setting\u528456) however this will change depending on which PC the program is being run on.
As the file will always be in the User Profile file I would like to the the Dos Variable USERPROFILE within my java code so that it always finds the file no matter what the staff number is (ie. u582456)
Any help would be appreciated,
Johann

Thanks for the info but I do not seem to get it to work. I am coding in Eclipse and I believe I am using JDK 1.3 but not 100%.
This is the code I have so far:
public class Test {
    public static void main(String[] args) {
    File file = new File("D:\\Work\\Text.txt");
    FileInputStream fis = null;
    BufferedInputStream bis = null;
    DataInputStream dis = null;
    try {
      fis = new FileInputStream(file);
      // Here BufferedInputStream is added for fast reading.
      bis = new BufferedInputStream(fis);
      dis = new DataInputStream(bis);
      // dis.available() returns 0 if the file does not have more lines.
      while (dis.available() != 0) {
      // this statement reads the line from the file and print it to
        // the console.
        System.out.println(dis.readLine());
      // dispose all the resources after using them.
      fis.close();
      bis.close();
      dis.close();
    } catch (FileNotFoundException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
The result of this code is that it prints the text in the file Text.txt which is located in D:\Work.
However as previously stated I would like it to find the text file in the USERPROFILE folder as specified in each individual PCs Dos Variables.
Could you please advise further.
