Write a program (in Java) that prompts the user to enter a file name. The program checks whether the file exists. If so, change the file name by appending the date and time to the file. Pass the filename from the command line. Here is a sample run of the program:

java RenameFile c:\temp\Test.txt

Success. New file is c:\temp\Test.txtThu Aug 29 13_54_11 EDT 2013

java RenameFile c:\temp\Test.txt

The file does not exist
