PRG 420 Week 2 Individual Assignment  Coding a Program Containing if-then and switch

Resources:    • Week Two Coding Assignment Text File
For this assignment, you will apply what you learned in analyzing Java™ code so far in this course by writing your own Java™ program. The Java™ program you write should do the following:

   •  If input value is not between 3 and 5, display an informative error message 
  •  If input value is between 3 and 5, use a switch statement to display a message that identifies the correct polygon based on the number of sides matching the input number (e.g., triangle, rectangle, or polygon)
 Complete this assignment by doing the following:  
 1.  Download the linked Week Two Coding Assigment Text File.  
 2.  Read the file carefully, especially the explanatory comments of what the existing code does.   
3.  Add your name and the date in the multi-line comment header. 
  4.  Refer to the following linked Week Two Recommended Activity Text File to see examples of how to code all of the Java™ statements (i.e., switch, println(), and if-then-else) you will need to write to complete this assignment.  
 5.  Replace the following lines with Java code as directed in the file:    
   •  LINE 1      
 •  LINE 2  
 6.  Comment each line of code you add to explain what you intend the code to do.

PRG 420 Week 3 Individual Assignment  Analyzing a Program Containing Loops 

Resource:    • Week Three Analyze Assignment Text File
For this assignment, you will be analyzing the Java™ code in the linked Week Three Analyze Assignment Text File, and predicting the results. You will also examine both the code and the output for inconsistencies and clarity. This Java™ code includes examples of for, while, and do while loops. Carefully read through the code line by line, then answer the following questions in a Microsoft® Word document:  
 
1.  What is the output of the program as it is written?
2.  What improvement(s) could be made to this code to make the output clearer or more accurate, or to make the code easier to maintain?
 
 Note: You do not have to make the improvements in the Java™ program, although you certainly may. For this assignment, simply describe the things you see that would need to be improved to elevate the code and output to a more professional level. For the code, consider variable names and hardcoding. For the output, consider formatting/punctuation, repetition, accuracy of information, and wording.

Instructions: Resource: 
  Week Three Coding Assignment Text File (starter code for this assignment that includes placeholders) For this assignment, you will apply what you learned in analyzing for, while, and do-while loops by writing these statements yourself. The Java™ program you write should do the following:   
 •  Display a pyramid of asterisks onscreen (i.e., a nested for loop)   
 •  Display the integers 10 to 1 in decreasing order, one number per line (i.e., a while/do-whlie loop)   
 •  Add 7 until the sum becomes greater than 157, at which point the program should display both the sum and the number of 7s added

1.  Download the linked Week Three Coding Assignment Text File.   
 2.  Add comments to the code by typing your name and the date in the multi-line comment header. 
  3.  Replace the following lines with Java™ code as directed in the file:   
     •  LINE 1     
     •  LINE 2     
     •  LINE 3   
 4.  Comment each line of code you add to explain what you intend the code to do and why you chose each type of loop. 
  5.  Test and modify your Java™ program until it runs without errors and produces the results as described above.

PRG 420 Week 4 Individual Assignment Coding a Program Containing an Array 

For this assignment, you will apply what you learned in analyzing a simple Java™ program by writing your own Java™ program that creates and accesses an array of integers. The Java™ program you write should do the following:
 
1.      Create an array to hold 10 integers
 
2.      Ask the user for an integer. Note: This code has already been written for you.
 
3.      Populate the array.
 
Note: The first element should be the integer input by the user. The second through tenth elements should each be the previous element + 100. For example, if the user inputs 10, the first array value should be 10, the second 110, the third 210, and so on
Display the contents of the array on the screen in ascending index order.
 
Complete this assignment by doing the following:
 
1.      Download the linked Week Four Coding Assignment Text File.
 
2.      Read each line of the file carefully, including the detailed instructions at the top.

•  LINE 2
•  LINE 3
•  LINE 4
•  LINE 5
