I have a java question regarding get/set and overloading constructors:
The problem is my calculations are not happening. Can someone tell me what needs to be done to get the calculation to work?
Thanks in advance …. Samm

The output is:
After attempting to set to invalid Values (0 & 10) :
Area = 01×10=00
Perimeter = 2(01+10)=00
After attempting to set to invalid Values (10 & 21):
Area = 10×01=00
Perimeter = 2(10+01)=00
After attempting to set to invalid Values (99 & 99) :
Area = 01×01=00
Perimeter = 2(01+01)=00
After attempting to set to valid Values (10 & 10) :
Area = 10×10=00
Perimeter = 2(10+10)=00
BUILD SUCCESSFUL (total time: 2 seconds)

I am running 2 classes. Size2 and Size2 test. Size2 Contains the variables and methods, Size2Test outputs. Code is as follows:

Size2 :
