Question

IN JAVA

3 ZIPS, What Order?:
Write a program named ZipOrder that the reads in three zip codes from standard input and prints to standard output one of three words: "ASCENDING", "DESCENDING", "UNSORTED". The zip codes are guaranteed to be distinct from each other. In particular:

if each zip code read in is greater than to the previous one, "ASCENDING"  is printed.

if each zip code read in is less than to the previous one, "DESCENDING" is printed.

otherwise, "UNSORTED" is printed.

The program accomplishes this by reading the zip codes and passing them as arguments to a method named direction. This method returns a string ("ASCENDING", "DESCENDING", or "UNSORTED") that the program prints out. The function carries out the zip code order logic.

CONSTRAINT: You must define and use the method direction.

Answer 1

Implemented code as per the requirement. Please comment if you face any difficulty or if you need any modification.

Code:

======

import java.util.Scanner;

public class ZipOrder {

static Scanner sc;

static int len = 0;

static int[] zips;

public static void main(String[] args) {

sc = new Scanner(System.in);

System.out.print("How many zip codes do you want to enter? ");

len = Integer.parseInt(sc.nextLine());

zips = new int[len];

for(int i=0; i<len; i++) {

System.out.print("Enter zip code "+(i+1) + ": ");

zips[i] = Integer.parseInt(sc.nextLine());

}

direction(zips);

}

private static void direction(int[] zips) {

int count=0, count1=0;

for(int i=0; i<len-1; i++) {

if(zips[i]<=zips[i+1]) {

count++;

}

if(zips[i]>=zips[i+1]) {

count1++;

}

}

//System.out.println(count1+ " "+count+ " "+len);

if(count == len-1) {

System.out.println("ASCENDING");

}

else if(count1 == len-1) {

System.out.println("DESCENDING");

}

else {

System.out.println("UNSORTED");

}

}

}
