So what I'm aiming for here is to take the user's input as float and write code to split up that input into individual digits and use an array.

How would I go about doing this?

Here is what my code looks like currently:

import java.util.Scanner;
public class Asn8
{
	public static void main(String args[])
	{
		Scanner kb = new Scanner(System.in);
		String s1;
		System.out.println("Please enter the name on the check (First Last) : ");
		s1 = kb.nextLine();
		System.out.println("Please enter the amount for the check (as a float) : ");
		float f1 = kb.nextFloat();
		if(f1 < 0)
			System.out.println("Invalid amount : " + f1);
		System.out.println("\n------------------------------------------------------");
		System.out.println("\nPay to : " + s1 + "\t\t\t\t$" + f1);
	}
}

Here is the final output that was provided:

Please enter the name on the check (First Last): Maya Tolappa
Please enter the amount for the check (as a float): 123.45
 ---------------------------
Pay to : Maya Tolappa           $123.45 
one hundred twenty three dollars and  45 cents

The 123.45 which is input as a float is taken and displayed as "one hundred twenty three dollars and 45 cents"

It isn't supposed to just work for 123.45 but all floats.


All feedback is much appreciated,

Implement a new function that takes teh float and gives you back a string!
If you're unable to post the function's code with questions..

See the below code ..it should solve your purpose

import java.text.DecimalFormat;
import java.util.Scanner;
public class Asn8
{
	
	  private static final String[] tensNames = {
		    "",
		    " ten",
		    " twenty",
		    " thirty",
		    " forty",
		    " fifty",
		    " sixty",
		    " seventy",
		    " eighty",
		    " ninety"
		  };
	  
	  private static final String[] numNames = {
		    "",
		    " one",
		    " two",
		    " three",
		    " four",
		    " five",
		    " six",
		    " seven",
		    " eight",
		    " nine",
		    " ten",
		    " eleven",
		    " twelve",

		    " eighteen",
		    " nineteen"
		  };
	  
	  private static String convertLessThanOneThousand(int number) {
		    String soFar;

		    if (number % 100 < 20){
		      soFar = numNames[number % 100];
		      number /= 100;
		    }
		    else {
		      soFar = numNames[number % 10];
		      number /= 10;

		      soFar = tensNames[number % 10] + soFar;
		      number /= 10;
		    }
		    if (number == 0) return soFar;
		    return numNames[number] + " hundred" + soFar;
		  }
	  
	  
	  public static String convert(long number) {

		    result =  result + tradThousand;
		    

		    // remove extra spaces!

Don't just hand students completed code for their assignment. That's not how things are done here.

Thank you so much for the help. Everything makes a lot more sense now. I really appreciate it. :]

Sir..
May you please help me how to create a syntax for triful looping using java language.
