Q: Final touches on my Java code? I'm more than 90 percent done with my code... Wanna add a few things but I've got no idea how to proceed.  
This is my code so far... I have other classes as well, and I'm calling them in this code.

How would I do the following in my program?
 Each iteration should display the readings being generated for each temperature and humidity. At the end your program should display a summary of the simulation as follows:
Season: _________ (if random, then display Random:Summer for example)

1-  First temperature generated
2-  Last temperature generated
3-  Lowest temperature generated
4-  Highest temperature generated
5-  Total sum of all temperatures generated
6-  Average for the season

Humidity Type: _________ (if random, then display Random:Full for example)
1-  First humidity reading generated
2-  Last humidity reading generated
3-  Lowest humidity reading generated
4-  Highest humidity reading generated
5-  Total sum of all humidity readings generated
6-  Average humidity reading
