Simple way of reversing a number in java

Question

Hi everyone just had a simple quick question and would like some quick feedback. What would be a plain simple way for a beginner programmer to take for instance a 3 digit integer such as 745 and reverse it and print it out as 547? thanks in advance

What I mean is that the linked Q was changed in a way that made its accepted answer nonsensical (and plain wrong). I have reverted the edit ... but now the Q is no longer relevant to >>this<< Q. Hopefully a moderator will sort out this mess. — Stephen C, Apr 29 '17 at 02:59
