New to Java

First post on the forums so let me preface this with saying this is my first java attempt at anything. I have some minor programming background in C++. In short I have this program that is computing wind chill, but I have to validate two inputs from the user and then basically a repeat calculations via a YES_NO_OPTION. Now where I am running into difficulties is the do while loops.

1) the first to validate that the temp is between -58 and 41
2) the second to validate that mph is > 2
3) is if the user wants to calculate more

I for the life of me cannot seem to figure out how to get the validate loops (item 1, 2) to even run without errors...so I took them out, but I would like to have this in there...obviously. I am just not used to parsing strings and such so I am unsure how to take this into account for my do-while loop. I can get the error message to generate, but cant loop back to have the usere enter number again. My final issue is with the repeat via JOptionPane.YES_NO_OPTION. I have the do while already in my program and it runs, although it runs the same message when I click yes or no. If I click on yes it repeats, but shows my closing message. If i choose no then it displays my closing message and no repeat. It just seemed strange to me. If anyone can shed a bit of insight for me I would greatly appreciate it.
