Write a program in Java to convert number into words & print it

 Hi guys here is the solution cheers :) keep supporting by clicking on ads :p

import java.util.Scanner;
class Solution {
    public static void main(String args[]){
        Scanner sc=new Scanner(System.in);
        System.out.println("enter the number");
        int n=sc.nextInt();
        int n1=n,n2=n;
        int b=n1%10,a=n2/10; //  n1/10 means last digit is removed and n2%10 means last digit by modulus
 
        String[] single_digits = new String[]{"zero","one","two","three","four","five", "six","seven","eight","nine"};
        String[] two_digits = new String[]{"","ten","eleven","twelve","thirteen","fourteen","fifteen","sixteen","seventeen","eighteen", "nineteen"};
        String[] tens_multiple = new String[]{"","","twenty","thirty","forty","fifty","sixty", "seventy","eighty","ninety"};
        if(a==1)
        {
            System.out.println(two_digits[b+1]);
        }
        else if(b==0)
            System.out.println(tens_multiple[a]);
        else
            System.out.println(tens_multiple[a]+"-"+single_digits[b]);
    }//main
}   

Output: 

enter the number
