Blue Pelican Java Project 11... please help

Write a program that will allow a user to input his name. The prompt and input data would look something like this:
Please enter your name. Peter Ustinov

Using a for-loop and the String method, substring(...), produce a printout of the reversal of the name.

For example, the name Peter Ustinov would be:
vonitsu retep

Notice that the printout is in all lower-case. Use the String method, toLowerCase() to accomplish this.

Lol @ Cfag. This thread confirmed he's a 15 years old kid who uses inline assembly to write OMG OPTIMIZED shitty algorithms, and doesn't even understand the difference between length and concatenation, both of which by the way can be O(1) in better string systems.
