Question

For this assignment, you will be analyzing the Java™ code in the linked Week 3 Analyze Assignment Zip 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.

* Program Summary: For, while, and do-while loops
*
* This program demonstrates the syntax for the for, while, and do-while loops. It also
* contains comments that explain why a programmer would use a for loop over a while or do-while
* loop.
*
* Notice the increment operator (i++) and also notice the copious use of println() statements.
* Using System.out.println() is an excellent way to debug your code--especially if your loop code
* is giving unexpected results.

public static void main(String[] args) {
  
// for loops are a good choice when you have a specific number of values

for (int price=1; price<=10; price++) {
System.out.println("The 8% tax on " + price + " dollar(s) is " + "$" + (price * taxRate));
}
System.out.println(""); // Leave a blank space
  
// while loops are a good choice when you're looking through a pile of values
// and want to execute some logic while some condition is true.
// while loops MAY OR MAY NOT EVER EXECUTE, depending on the counter value.
int dollars=1;
System.out.println("WHILE LOOP - Here are the taxes on prices less than $5:");
while (dollars < 5) {
System.out.println("The 8% tax on " + dollars + " dollar(s) is $" + (dollars * taxRate));
dollars++;
}
System.out.println(""); // Leave a blank space
  
// do-while loops are also a good choice when you're looking through a pile of values
// and want to execute some logic while some condition is true.
// do while loops ALWAYS EXECUTE AT LEAST ONCE, no matter what the counter value.
// For example, in the code below, we want to print out the tax only on those
// amounts smaller than $1. But because we're using the do-while loop, the code
// will execute the body of the loop once before it even checks the condition! So
// we will get an INCORRECT PRINTOUT.
dollars=1;
  
System.out.println("DO-WHILE LOOP - Here are the taxes on prices less than $1:");
  
do {
System.out.println("The 8% tax on " + dollars + " dollar(s) is $" + (dollars * 0.08));
dollars++;
} while (dollars < 1);
}
}

Answer 1

The out put produced by the program:

Here we are printing the 8% value as hard coded instead of that we can take it into a constant variable and use it so that in future even if you change the it will easy to update because if we update at one place than that will change every where
