Java Program convert number to words

Here we write a Java program convert number to words.we have perform following step :-

First we create the Scanner class object to pass user input.
From sc.nextInt() method take user input as Integer type and store in userNumber variable.
Inside first if condition we check user input should be less than 1 and greater than 100, if it is then print wrong number.
Inside else if condition we check user input should be between 1 to 19,then print number to words.
Inside second else if condition we check user input should be between 20 to 99, then print number to words.
Here we get the divide the number by 10 and store the divided in digit1.now pass this digit1 in array type string str1.
Now we modulo the number by 10 and store in digit2,after that pass this digit2 in array type string str2.
After that all number is comparing with string array index value and print the number in words.

				
					import java.util.Scanner;

public class A {
	public static void main(String[] args) {

		int userNumber, digit1, digit2;
		Scanner sc = new Scanner(System.in);

		String str1[] = { "", "", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "nenety" };
		String str2[] = { "", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven",
				"twelve", "thirteen", "fourteen", "fifteen", "sixteen", "eighteen", "ninteen" };
		
		System.out.println("Enter the user number between 1 to 99");
		userNumber = sc.nextInt();

		if ((userNumber < 1) || (userNumber > 100)) {
			System.out.println("wrong number");
		} else if ((userNumber >= 1) && (userNumber <= 19)) {
			System.out.println("Number in words :- " + str2[userNumber]);
		} else if ((userNumber >= 20) && (userNumber <= 99)) {
			digit1 = userNumber / 10;
			digit2 = userNumber % 10;
			System.out.println("print number to words :- " + str1[digit1] + " " + str2[digit2]);
		}
	}
}

Output :-
Enter the user number between 1 to 99
56
print number to words :- fifty six
