Question

[JAVA] How to do this problem. we have to tell if given list of three number is in ascending, descending or no order.

Instructions

You will be given three integers: ?, ? and ? (read in for you). Then you will be given two boolean values that tell you which way the numbers are going - if the numbers are in increasing order or in decreasing order, respectively.

Details

Input

• The program reads in:

  • a sequence of three integers: ?, ? and ?

  • boolean isIncreasing: set to True if the sequence of integers is increasing, i.e. ?<?<? (note, we are reading in either 0 for False or 1 for True)

  • boolean isDecreasing: set to true if the sequence of integers is decreasing, i.e. ?>?>?

Processing

• Based on the boolean values read in determine if the sequence of integers is increasing, decreasing or neither.

Output

• The original order is output for you.
• If the sequence of integers is increasing, output “The numbers are increasing”
  
    "The numbers are strictly increasing."
  
• If they are decreasing, output “The numbers are decreasing”
  
    "The numbers are strictly decreasing."
  
• Otherwise, output “No obvious order”  
  
    "There is no strict order."

Given code:

import java.util.Scanner;

public class PoD {
   public static void main (String [] args) {
      
  
       Scanner in = new Scanner (System.in);
      
       //Input
       int i = in.nextInt();
       int j = in.nextInt();
       int k = in.nextInt();
      
       boolean isIncreasing = in.nextInt() == 1 ? true : false;
       boolean isDecreasing = in.nextInt() == 1 ? true : false;
      
       System.out.println("Original order: " + i + " " + j + " " + k);

  
if ( boolean isIncreasing = 1) {
   System.out.println("The numbers are strictly increasing.");
}
else if ( boolean isDecreasing = 1) {
   System.out.println("The numbers are strictly decreasing.");
}
       else {
           System.out.println("There is no strict order.");
       }

      
   }
}

import java.util.Scanner;

public class PoD {
   public static void main (String [] args) {
      
  
       Scanner in = new Scanner (System.in);
      
       //Input
       int i = in.nextInt();
       int j = in.nextInt();
       int k = in.nextInt();
      
       boolean isIncreasing = in.nextInt() == 1 ? true : false;
       boolean isDecreasing = in.nextInt() == 1 ? true : false;
      
       System.out.println("Original order: " + i + " " + j + " " + k);


  
if (isIncreasing) { 
   System.out.println("The numbers are strictly increasing.");
}
else if (isDecreasing) { 
   System.out.println("The numbers are strictly decreasing.");
}
       else {
           System.out.println("There is no strict order.");
       }


      
   }
}

You just made a small mistake in "if" and "else if" conditions .

You already declared "isIncreasing" and "isDecreasing" variables so you don't need to say "boolean" again and you can't give "isIncreasing = 1" in conditions

I will submit my output screenshot below

Hope this will be helpful..
