Question

A. Write a class that declares a variable named inches that holds a length in inches,
and assign a value. Display the value in feet and inches; for example, 86 inches
becomes 7 feet and 2 inches. Be sure to use a named constant where appropriate.
Save the class as InchesToFeet.java.
B. Write an interactive version of the InchesToFeet class that accepts the inches
value from a user. Save the class as InchesToFeetInteractive.java.

Answer 1

Answer:

A.

public class Main{

public static void main(String[] args) {

 final int divisor = 12;

 int inches = 86 ,feet;

 feet =inches/divisor;

 inches = inches%divisor;

 System.out.print(feet+" feets "+inches+" inches");

}

}

B.

import java.util.*;

public class InchesToFeetInteractive{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 final int divisor = 12;

 int inches,feet;

 System.out.print("Measurement in Inches: ");

 inches = input.nextInt();

 feet =inches/divisor;

 inches = inches%divisor;

 System.out.print(feet+" feets "+inches+" inches");

}

}

Explanation:

Both classes use the same algorithm; however, the slight difference is that

(A) assumes a values of inch measure while (B) prompts user for input

That is show in the differences below

A)

int inches = 86 ,feet; ---> This initializes inches to 86;

B)

This prompts user for measurement in Inches

 System.out.print("Measurement in Inches: ");

This gets the measurement

 inches = input.nextInt();

The next lines are common in both classes

This declares and initializes a constant which is used in the conversion

 final int divisor = 12;

This calculates the number of feet in the user input

 feet =inches/divisor;

This gets the remainder inches, if any. It uses % to calculate the remainder

 inches = inches%divisor;

This prints the required output

 System.out.print(feet+" feets "+inches+" inches");
