PRG 420 Uop Courses PRG 420 ENTIRE COURSE PRG 420 WEEK 1 DQ 1 • PRG 420 Week 1 Individual • Assignment Hello world • PRG 420 Week 1 DQ 1 • PRG 420 Week 1 DQ 2 • PRG 420 Week 1 DQ 3 • Watch the first and second videos for Week 1. • Explain a little about the Java Virtual Machine, what it executes, how it might be similar to any other language, and how it is different from a native language, such as C++.

PRG 420 Uop Courses PRG 420 WEEK 1 DQ 2 PRG 420 WEEK 1 DQ 3 • Java is a portable language, and being an object-oriented programming language, it also encourages component reusability. • How does Java achieve these two important features? How are these features desirable in modern software engineering? • You are a bank manager and you are helping a new bank teller understand the kind of accounts the bank offers. If a customer comes in asking to open a new savings account, the teller needs to ask what kind of account--passbook savings or certificate of deposit--the customer would like to open. • Remind the customer that all accounts with our bank are insured by the FDIC.

PRG 420 Uop Courses PRG 420 Week 1 Individual Assignment Hello world PRG 420 WEEK 2 DQ 1 • Create a program in Java™ that displays “Hello world!” Take a screen shot that shows the program’s successful compilation and execution. Then submit your program along with the screen shot. • Please watch the first three videos for Week 2 (around 40 minutes). • Explain how an outside class may be given access to find the value of a private instance variable, or to change the value of a private instance variable. Why does this add value to your program?

PRG 420 Uop Courses PRG 420 WEEK 2 DQ 2 PRG 420 WEEK 2 DQ 3 • What are the three types of errors that you can encounter in a Java™ program? Describe them, and explain how you would minimize the errors. • What are some examples of errors that you have seen before? • A class is a blueprint for an object. A class may have a default constructor, a constructor with arguments, accessor methods, mutator methods, public fields, and private fields. • Choose a category (such as animal, vehicle, and so on) and describe how you would design a class for it.

PRG 420 Uop Courses PRG 420 Week 2 Individual Assignment Netbeans Project (annual compensation) PRG 420 WEEK 3 DQ 1 • Write a Java™ application using NetBeans™ Integrated Development Environment (IDE) that calculates the total annual compensation of a salesperson. • A salesperson will earn a fixed salary of $50,000 • A salesperson will also receive a commission as a sales incentive. Commission is a percentage of the salesperson’s annual sales. The current commission is 5 % of total sales. • Please watch the first and the fifth (next to the last) videos for Week 3 (feel free to use the transcripts, too!) . Tell me about the similarities between the conditionals in if statements and the conditionals in while statements.

PRG 420 Uop Courses PRG 420 WEEK 3 DQ 2 PRG 420 WEEK 3 DQ 3 • Convert the following program from for loop to while loop. class ArithmeticProgression{ public static void main (String [] args) {int sum = 0; for (inti = 1; i <= 1000; i++) { sum = sum + i;System.out.println(Integer.toString(sum)); } }} • There are 3 kinds of loops—for loop, while loop, and do while loop. • Under which circumstances would each kind of loop be more appropriate? • Explain your answers using specific examples.

PRG 420 Uop Courses PRG 420 WEEK 3 DQ 4 PRG 420 Week 3 Individual Assignment Netbeans Project (annual compensation with commission) • Consider the following conditions: • CONDITION 1: while ( !(cChoice == 'Q' || cChoice == 'q') )CONDITION 2: while ( cChoice != 'Q' || cChoice != 'q' ) • Do Conditions 1 and 2 give the same result? What tool or technique would you use to explain the result? • Modify the Week Two Java™ application using Java™ NetBeans™ IDE to meet these additional and changed business requirements: • The company has recently changed its total annual compensation policy to improve sales

PRG 420 Uop Courses PRG 420 WEEK 4 DQ 1 PRG 420 WEEK 4 DQ 2 • Assuming you want an array (named many) of seven ints what would be the easiest way to write the code if you wanted many to contain all zeros? • What if you wanted many to contain a selection of seven values, that were not all zeros? • What would be the subscripts of all the elements of many? • What is the difference between arrays and Array List? • What are the advantages and disadvantages of an Array List, and when should you use an Array List over a simple array?

PRG 420 Uop Courses PRG 420 WEEK 4 DQ 3 PRG 420 WEEK 4 DQ 2 • What is the difference between string and StringBuilder? What are the advantages and disadvantages of a StringBuilder, and when should you use a StringBuilder over a simple String? • Modify the Week Three Java™ application using Java™ NetBeans™ IDE to meet these additional and changed business requirements: • The application will now compare the total annual compensation of at least two salespersons. • It will calculate the additional amount of sales that each salesperson must achieve to match or exceed the higher of the two earners.

PRG 420 Uop Courses PRG 420 WEEK 5 DQ 1 PRG 420 WEEK 5 DQ 2 • Please explain one use for a static variable in a class. Please explain how you might use one static method ( not main() ) in a class. • In your opinion, what are the three biggest challenges in planning and designing a solution for a programming problem? • What can you do to overcome these challenges? How would you apply these techniques to the programs in this class?

PRG 420 Uop Courses PRG 420 WEEK 5 DQ 3 PRG 420 WEEK 5 TEAM ASSIGNMENT RESUABILITY (2 PAPERS) • Using an example from your work or daily life, describe an "is-a" relationship. Why is an "is-a" relationship important when designing an inheritance between classes? • In the real world, an entire program is rarely written from scratch. It is • very likely that there are classes or methods that already exist. The • key to using these existing modules successfully depends on how • modularly the classes or methods are written. • In this Learning Team assignment, your mission is to take a section • of one team member’s Week Four program and replace a similar
