Creating a temporary file in the user computer

Question

Hi everyone,
I want to create a new file using:
File folder = new File(folderString);
when folderString should be a folder where all temporary files of the user are saved (its a dynpage code).
So I found the following code in <b>JavaScript</b>:
var  cTemporaryFolder = 2,tmpdir='';
var fso;
fso     = new ActiveXObject('Scripting.FileSystemObject');
var fso;
tmpdir     = fso.GetSpecialFolder(cTemporaryFolder);
But how do I combine the code with the statement
File folder = new File(folderString);
(I eventually need: folderString = tmpdir - but one variable knows <b>java</b> and the other <b>javascript</b>)
Thanks so much.
I promise to award points...

Hi Ruthie,
Try out this code
try{
// Create a temporary file object
File f = new File("d://TestTemp");
File tempFile = File.createTempFile("mail", "temp",f);
System.out.println("Created temporary file: " + tempFile + "\n");
// Delete temp file when program exits
tempFile.deleteOnExit();
// Write to temporary file
BufferedWriter out = new BufferedWriter(new FileWriter(tempFile));
out.write("TEMP FILE: " + tempFile);
out.close();
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Press any key");
br.read();
System.out.println("Temp File will be deleted");
catch(IOException e) {
e.printStackTrace();
Now, the temp file will be created in d:\TestTemp\ folder. Before pressing any key just check in this folder. You will see the temp file. Pressing any key will exit the program. After this check the d:\TestTemp\ folder, the tempfile will be deleted.
