Description
Part A: This question is to be submitted to the instructor in the form of a Word (or Open
Office) document containing the Java code and appropriate screen capture(s) of the output.
The file name must be in the form ASSIGN5A_YourName where ‘YourName’ is your last
name followed by your first name with no space. Upload the file to CMS.
[15 marks] Given two strings representing numbers of indeterminate length, create a
program that provides the sum of two numbers. The program must use Strings to
hold the numbers, String methods (like length(), substring(), charAt()…) to manipulate
the values, and two different styles of loops (for, while, do-while).
Please enter a number: 123456
Please enter a second number: 789012
Addition: 123456
+ 789012
= 912468

Please enter a second number: 789012345678901234567890123456
Addition: 123456789012345678901234567890
+ 009012345678901234567890123456
= 132469134691246913469124691346
Show screen captures for both of the two numbers above plus the following
additional two calculations:
918273645546372819 + 2738495061728349
121212121212 + 98989898989898

Use at least two different loops (while, do-while, and for) in your program. Printf can
help with the formatting (See section 4.6).

Part B: Write code and test the solutions for the following problems from the textbook.
Submit the .java files for each question to CMS. The answers are due on October 30th and the
programs are to be demonstrated to the Teaching Assistant (Tim) by November 6
th. He will
ask questions to make sure you understand the material. (HINT: If you demonstrate your
programs before the due date, Tim can give you an opportunity to fix errors and redemonstrate).
[10 marks] Problem 5.21, page 194
Use printf to format the output (Section 4.6)
[15 marks] Problem 5.43, page 199
Make three versions of this program – one demonstrating the use of each of the loops
styles (FOR, WHILE and DO…WHILE).
