​The activity is meant to test your understanding on how to implement decision making in
your programs using the if-else, if-else-if ladder and the switch statement.
If you do not have Java installed on your laptop, you can use an internet based/online Java
compiler to do your work. Once done, copy the source code, paste it into MS word
document which you then upload to the system. You can also save and upload screen shots
with your code. You should only email your work if you are really not able to upload it to the
system. You have enough time to complete the activity hence late work will not be
marked and excuses will not be accepted.
Create one program that will do the following:
a) Receive input of three decimal numbers from the user (use scanner class for input),
compare them and display which one is the greatest number and which one is the
smallest number.
E. g.
Input:
45, 30, 90
Output:
90 is the greatest number
30 is the smallest number (10 marks)
b) Receive an integer number between 1 and 12 (use scanner class for input), compare
it with a list of cases given representing the 12 months of the year, then display
which month of the year it is depending on the number entered by the user.
E. g. Case 1: January
Case 2: February
Case 3: March
Case 4: April …………
If the user enters 3, the system will display that the month is March
