or is for a Rectangle.
Depending on that input – the program must call either the Triangle method or the
Rectangle method.
Each of those methods must receive 2 input fields from the user – one for base and one
for height in order to calculate the area and then to print that area and the height and
base from inside the method.

#2 Write a java program making use of methods that finds the smallest of any three
numbers that the user inputs. You must use JoptionPane to input the three numbers.

numbers.
A second method must be used to print out that smallest number found.

#3 Write a java program which uses methods for calculating the sum of any 5 nonzero integer digits that are input. The program must use scanner for input of the 5
digits.
Two Methods must be used, one for calculating the sum of the 5 digits & the other for
