Convert Human Readable Time Format to Unix Time & Java Milliseconds ( (Java Code))

I just wrote a java program to convert Human Readable Time Format to Unix Time & Java Milliseconds ( (Java Code)).

The code can be accessed here.

I also put it as follows to make it searchable:

To test it, you can convert the milliseconds back to human readable time format here.
