Create Temp File

     

In this section, you will learn how a temporary file is created to the default directory. 

A temporary file is a file that is created to store information temporarily so that the memory can be freed for other purposes. It is beneficial and secure to prevent loss of data when a program performs certain functions. For example, an application "Word" automatically determines where and when temporary files are to be created. The temporary files only exist during the current session of an application as the name suggest "temp".  When the application is shut down, all temporary files are first closed and then deleted.

Description of program:

The following code of program will help you in creating a Temporary File to your default directory. Here we have created a temporary file object. Then we have used a method to get the entire path of the temp file which gets created. The method is tempFile.getAbsolutePath();. We have also used a try and catch block here to catch the exception on occurrence. And if the file could not be created then we will get a message that "temp file not created".

import java.io.File;
import java.io.FileWriter;
import java.io.BufferedWriter;
import java.io.IOException;

public class CTFile {
  public static void main(String[] args){
  File tempFile = null;
  
  try {
  tempFile = File.createTempFile("MyFile.txt"".tmp" );
  System.out.print("Created temporary file with name ");
  System.out.println(tempFile.getAbsolutePath());
  catch (IOException ex) {

  System.err.println("Cannot create temp file: " + ex.getMessage());
  finally {
  if (tempFile != null) {
  }
  }
  }
}

Output of the program:

C:\unique>javac CTFile.java

C:\unique>java CTFile
Created temporary file with name C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\MyFile.txt49
754.tmp

C:\unique>

First, if you have a web service rnnniug on you LOCAL computer. Shut it down temporarily while your looking at the online on. If simply doing this doesnt help you may have a hosts file entry that is pointing you to the wrong place (your local machine).
