io - open temp file in java

I'm writing string to temporary file (temp.txt) and I want that file should open after clicking button of my awt window it should delete when I close that file (after opening that file), how can I do this?

This is the code that I have been using to create temporary file in Java:

File temp = File.createTempFile("temp",".txt");

FileWriter fileoutput = new FileWriter(temp);
Bufferedwriter buffout = new BufferedWriter(fileoutput);
See Question&Answers more detail:os

A file created by:

File temp = File.createTempFile("temp",".txt");

Will not be deleted, see javadoc, you have to call

temp.deleteOnExit();

so the JVM will delete the file on exit...
