-
Become familiar with Java program elements:
-
Variable types
-
-
Operators and Expressions o Control structures
-
o Input & Output statements (inc. StdIn, StdOut from the textbook) o Functions
-
Be able to use Eclipse to create, debug and run basic Java programs.
-
Be able to upload the required files to D2L.
You are to write a Java program for each of the following problems. Name your projects as: csc402hw1a, csc402hw1b, csc402hw1c, csc402hw1d corresponding to problems a-d below.
Once you have a program working, run it using the data indicated below, then copy/paste the console output into the top of your java source file in a comment block, right below your name. Upload the .java file to the submission folder.
-
Write a program to prompt the user for 2 floating point numbers, A & B. The program should print, on separate lines:
-
•
The sum of the two numbers A + B
Input: 3.5 , 4.2
• The difference of the two numbers A – B
•
The quotient (first/second) A / B
•
The quantity: AB, Hint pow( )
B) Write a program to prompt the user for a positive integer, N. The program will repeatedly divide the input in half, discarding any fractional part, until it becomes 1. The program should print on separate lines:
|
• the sequence of computed values, one per line |
||||
|
Run twice |
||||
|
• the number of iterations required |
||||
|
Input1: 8 Input 2 19 |
||||
|
• the value of log2(N) |
||||
|
C) Write a program that will prompt the user to enter GPA |
||||
|
values one per line, stopping when the user enters a negative |
Input: |
|||
|
value. Print the following on separate lines: |
4.0 |
|||
|
• The number of valid GPAs entered. |
3.7 |
|||
|
• The sum of the GPAs |
2.9 |
|||
|
• The average GPA |
3.5 |
|||
|
-1 |

-
Write a function with one integer parameter, N. The function
will compute and return the sum of the integers from 1 to N. Name the function: sumInts.
Then write a complete program using this function. The main function will prompt the user for an integer, N. The main function will call the sumInts function for every value M from 1 up to N and print out:
-
The value M
-
The result of sumInts(M)
-
The value of (M+1)*M / 2
Input: 9
