need help converting numbers to word

[miatech]

guys, I wrote this program that converts numbers to words eq: 4914 to "four thousand and nine hundred and fourteen"; however, I'm having problems with the toString method. Is not printing correctly some numbers. the functions and their return type can't be changed. I need help with the toString method that actually puts all the words together. I appreciate any help.

public class Numbers {
 
  
 
    //getting single digit number
    private int getOnes()
    {
        one = value % 10;
        return one;
    }
 
    //getting tens numbers
    private int getTens()
    {
        ten = value % 100;
        ten /= 10;
        return ten;
    }
 
    //getting hundreds numbers
    private int getHundreds()
    {
        hundred = value % 1000;
        hundred /= 100;
        return hundred;
    }
 
    //getting thousands numbers
    private int getThousands()
    {
        thousand = value % 10000;
        thousand /= 1000;
        return thousand;
    }
 
    //converting and returning string of ones 
    private String digitsToString(int one)
    {
        return SINGLE_DIGITS_WORDS[one];        
    }
 
    //converting and returning strings of tens and teens
    private String tensAndOnesToString(int ten, int one)
    {
        if(ten == 1)//if number is a teen return, else return tens
