Chapter 2, Problem 1RE

Write declarations for storing the following quantities. Choose between integers and floating-point numbers. Declare constants when appropriate.

  1. a. The number of days per week
  2. b. The number of days until the end of the semester
  3. c. The number of centimeters in an inch
  4. d. The height of the tallest person in your class, in centimeters

a.

Explanation of Solution

 Declaration for the first statement:

  • The given statement is “The number of days per week”.
  • Totally, there are seven days in a week and there is no change of days in a week.
  • Hence, the number of days in a week is fixed forever.
  • The declaration for storing the number of days in a week is as follows:

/* Declaration for storing the number of days in a week */

        public static final int DAYS_PER_WEEK = 7;

Explanation of Solution

 Declaration for the second statement:

  • The given statement is “The number of days until the end of the semester”.
  • The number of days in a semester varies from time to time and the days may either increase or decrease based on the semester time-table.
  • Hence, the number of days in a semester is an integer variable.
  • The declaration for storing the number of days in a semester is as follows:

/* Declaration for storing the number of days in a semester */

        public int daysInSemester;

Explanation of Solution

 Declaration for the third statement:

  • The given statement is “The number of centimeters in an inch”.
  • The number of centimeters in an inch is a fixed type of float value.
  • The declaration for storing the number of centimeter in an inch is as follows:

/* Declaration for storing the number of centimeters in an inch */

public static final float CENTIMETERS_IN_INCH = 2.54;

d.

Expert Solution

Explanation of Solution

 Declaration for the fourth statement:

  • The given statement is “The height of the tallest person in your class, in centimeters”.
  • The height of the tallest person in a class is a float value since height contains decimal values.
  • The height of a person varies over time.
  • Hence, the height of a person is not fixed and it is float type value.
  • The declaration for storing the height of the tallest person in a class is as follows:

/* Declaration for storing the height of the tallest person in a class*/

        public float tallestHeight;
