16.13. NumberGroup - Part B

Part b. A range represents a number group that contains all (and only) the integers between a minimum value and a maximum value, inclusive. Write the Range class, which is a NumberGroup. The Range class represents the group of int values that range from a given minimum value up through a given maximum value, inclusive. For example, the declaration NumberGroup range1 = new Range(-3, 2); represents the group of integer values -3, -2, -1, 0, 1, 2.

Write the complete Range class. Include all necessary instance variables and methods as well as a constructor that takes two int parameters. The first parameter represents the minimum value, and the second parameter represents the maximum value of the range. You may assume that the minimum is less than or equal to the maximum.

16.13.1. Try and Solve It

Write the class Range below.

The code below has a main method for testing the NumberGroup method.

public class Range implements NumberGroup { //Write the Range class here! //Main method to test the class public static void main(String[] args) { System.out.println("This is testing the constructor"); Range test = Range(5, 8); System.out.println("The program says the minimum is " + test.getMin() + ", it really should be 5."; System.out.println("The program says the maximum is " + test.getMax() + ", it really should be 8."; System.out.println("This is testing the contains function."); System.out.println("The program says that 6 is within the range of the function, which is correct."); } // end of main } // end of class
