    The array was to hold the Strings for the names of the numbers
    and the number was used to index into the array.
    For example the first element in the array would be "zero"
    If you don't understand my answer, don't ignore it, ask a question.

    First, you need an array to map number to string, like this:
    String[] number = {"zero","one","two","three","four","five","six","seven","eight","nine"};

    And then you need to split your string to list of word. (token your string)
    String[] words = your_data.split(" ");

    After that you need to go through your words & check if there has any number from 0->9
    for(String word : words){
      //check word & replace here
    }
    Ok, by now you need to check if it's number & replace it.
    if(word.lengh() == 1){
       char c = word.charAt(0);
       if(c >= '0' && c <='9')
         return number[c - '0'];
    }

    Incase you know ascii code, you code compare like that:

    int charCode = word.charAt(0);
    if( charCode >= 48 && charCode <= 57){
       return number[charCode - 48];
    }

    I think all would be clearly now, you need to think about it again & again and do coding by your self.
    If you need any help, just post your code then I & others would happy to help you.

    Happy Coding
