Question

In.java

In this program write a method called upDown that takes three integers as arguments and returns one of these 3 strings:

• "increasing" if they are in strictly increasing order (note that 3,3,4 - are not strictly increasing),
• "decreasing" if they are in strictly decreasing order.
• "none" otherwise.
  I recommend you use a complex condition to check for this (that is, have a single if statement with one big question).

In the main method do the following:

• read three integers from the user and call upDown for those integers, save the result in a variable, res1, and then print it.
• read again three integers from the user and call upDown for those integers, save the result in another variable, res2, and then print it.
• compare res1 and res2 and print "same" or "different"

read three integers from the user and call upDown for those integers, save the result in a variable, res1, and then print it.

---------- Sample run 1:
Enter three integers separated by spaces: 2 0 9
These numbers are in order: none
Enter three integers separated by spaces: 17 90 567
These numbers are in order: increasing
different

---------- Sample run 2:
Enter three integers separated by spaces: 90 9 1
These numbers are in order: decreasing
Enter three integers separated by spaces: 7 3 1
These numbers are in order: decreasing
same

---------- Sample run 3:
Enter three integers separated by spaces: 3 3 4
These numbers are in order: none
Enter three integers separated by spaces: 8 1 16
These numbers are in order: none
same

        }
        return s;

       String res1,res2;
       Scanner sc=new Scanner(System.in);
       System.out.print("Enter three integers separated by spaces: ");
       //reading integers from the user
       a=sc.nextInt();
       b=sc.nextInt();
       c=sc.nextInt();
       res1=upDown(a,b,c);
       System.out.println("These numbers are in order: "+res1);
      
       System.out.print("Enter three integers separated by spaces: ");
       //reading integers from the user
       d=sc.nextInt();
       e=sc.nextInt();
       f=sc.nextInt();
       res2=upDown(d,e,f);
       System.out.println("These numbers are in order: "+res2);
       //compare if two results are equal or not
       if(res1.equals(res2))
       {
            //if two strings are equal
            System.out.println("same");
       }
       else
       {
             System.out.println("different");
