deleteOnExit()


The java.io.File.deleteOnExit() method deletes the file or directory defined by the abstract path name when the virtual machine terminates. Files or directories are deleted in the reverse order as they are registered.

Syntax:
public void deleteOnExit()


Example:

/* java example */
import java.io.File;

public class FileDemo {
   public static void main(String[] args) {
      
      File f = null;
            
      try{
         // creates temporary file
         f = File.createTempFile("tmp", ".txt");
         
         // prints absolute path
         System.out.println("File path: "+f.getAbsolutePath());
         
         // deletes file when the virtual machine terminate
         f.deleteOnExit();
         
         // creates temporary file
         f = File.createTempFile("tmp", null);
         
         // prints absolute path
         System.out.print("File path: "+f.getAbsolutePath());
         
         // deletes file when the virtual machine terminate
         f.deleteOnExit();
         
      }catch(Exception e){
         // if any error occurs
         e.printStackTrace();
      }
   }
}
