Question

What order? (function templates) Define a generic function called CheckOrder() that checks if four items are in ascending, neither, or descending order. The function should return -1 if the items are in ascending order, 0 if the items are unordered, and 1 if the items are in descending order. The program reads four items from input and outputs if the items are ordered. The items can be different types, including integers, strings, characters, or doubles. Ex. If the input is:

Answer 1

Answer:

Explanation:

The following code was written in Java and creates the generic class to allow you to compare any type of data structure. Three different test cases were used using both integers and strings. The first is an ascending list of integers, the second is a descending list of integers, and the third is an unordered list of strings. The output can be seen in the attached image below.

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Order: " + checkOrder(10, 22, 51, 53));

       System.out.println("Order: " + checkOrder(55, 44, 33, 22));

       System.out.println("Order: " + checkOrder("John", " Gabriel", "Daniela", "Zendaya"));

   }

   public static <E extends Comparable<E>> int checkOrder(E var1, E var2, E var3, E var4) {

       E prevVar = var1;

       if (var2.compareTo(prevVar) > 0) {

           prevVar = var2;

       } else {

           if (var3.compareTo(prevVar) < 0) {

               prevVar = var3;

           } else {

               return 0;

           }

           if (var4.compareTo(prevVar) < 0) {

               return 1;

           }  else {

               return 0;

           }

       }

       if (var3.compareTo(prevVar) > 0) {

           prevVar = var3;

       }

       if (var4.compareTo(prevVar) > 0) {

           return -1;

       }

       return 0;

   }

}
