Bouncy Number in Java

A number is said to be a Bouncy number if the digits of the number are unsorted.

For example:

1728 is a bouncy number because the digits are unsorted.

2289 is not a bouncy number because the digits are sorted in ascending order.

74410 is not a bouncy number because the digits are sorted in descending order.

All numbers below 100 are not bouncy numbers.

Write a program in Java to accept a number and check whether it is a bouncy number or not.

import java.util.Scanner;
class Bouncy{
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("N = ");
        int n = Integer.parseInt(in.nextLine());
        int len = String.valueOf(n).length();
        int a[] = new int[len];
        int j = 0;
        for(int i = n; i != 0; i /= 10)
            a[j++] = i % 10;
        boolean asc = true;
        for(int i = 0; i < a.length - 1; i++){
            if(a[i] > a[i + 1]){
                asc = false;
                break;
            }
        }
        boolean desc = true;
        for(int i = 0; i < a.length - 1; i++){
            if(a[i] < a[i + 1]){
                desc = false;
                break;
            }
        }
        if(!asc && !desc)
            System.out.println("Bouncy number!");
        else
            System.out.println("Not a Bouncy number.");
    }
}
