Create temporary file

/*
  Create temporary file
  This Java example shows how to create a new temporary file using
  createTempFile method of Java File class.

     * To create temporary file use,
     * static File createTempFile(String namePrefix, String nameSuffix) method
     * of Java File class,
     *
     * where namePrefix is a prefix string used to generate
     * a file's name and must be atleast 3 characters long and nameSuffix is a
     * suffix string used to generate suffix of the temporary file name. Suffix
     * may be null, and in that case default ".tmp" will be used as a suffix.

Typical output would be
Temporary file without suffix extension: C:\Temp\JavaTemp45096.tmp
Temporary file with suffix extension: C:\Temp\JavaTemp45097.javatemp
