Stuck, need help please

Hi, i'm doing this program, and im currently stuck.

For this assignment you are to print a table that gives frequencies of the digits 0 through 9 in a typed English text. To keep things simple and concrete, your job will be to print the digit frequencies for multiple lines of text you enter from the keyboard. More specifically, you program should continue entering lines of text until you type two Returns in a row. Here is some sample interaction:


Enter lines of text. Type two Returns in a row to end

Tips/Further Qualifications

Use the input style that appears in Program Backwards in Chapter 7. (It accepts multiple lines of text).
You MUST do this assignment with two classes: a driver, which includes main and handles the input, and is called DigitDriver; and a principal processing class, called DigitCounter. Objects in the DigitCounter class are responsible for handling the character processing. DigitCounter must have an array instance variable which acts as a scoreboard, tallying digits when they are encountered in the entered text.
Remember that if someDigit is a char variable that holds a digit, then (someDigit-'0') gives the numerical position of someDigit among all digits. Thus if someDigit holds a 4, then (someDigit - '0') = 4. Use this fact to drive your array indexing.
Use the static method isDigit from the Character class to determine when you've come across a digit.
Your DigitCounter code must include and make use of a method called processString, which is passed a string as a parameter - a typed line of input - and which is responsible for finding and then tallying occurrences of digits in the parameter.
Be sure to comment your code.

This is what i have so far
main

import java.util.Scanner;

public class DigitDriver{
  public static void main(String[] args){
    String[] stringArray = new String[100]; // setting string
    
    System.out.println("Enter text. Type two Returns in a row to end"); // Screen promt
    Scanner scan = new Scanner(System.in); // enable input from keyboard
    int pos = 0;
    String d = " ";
    while(d.length()>0){
      d=scan.nextLine();
      stringArray[pos]=d;
      pos++;
    } // get input from keyboard
    
    DigitCounter myDigit = new DigitCounter(countArray);
    countArray.processString(); 
    
    System.out.println("Digit Frequencies");
    for(int i=0; i<=9; i++){
      System.out.println("-------------");
      System.out.println(i + " " + countArray[i]);
    } // print the table
  }
}

and here's the class

public class DigitCounter{
  char[] d;
  private String digit;
  
  public DigitCounter(char d){
     this.d = new someDigit[digit];
     
  }
    
    
  

  public String processString(String digit){
    
    for(int j=0; j<=9; j++){
      someDigit[j]=0;
    }
    for(int k=0; k<someDigit.length(); k++){
      if(Character.isDigit(someDigit.charAt(k))){
       
        someDigit[digit]++;
  return digit;}
   } 
  }

I'm stuck and I'm not sure if what I have is even right or on the right path. Help would be great, Thanks

Search this forum (top right corner) for a thread titled "digit counter"; this problem was posted (and solved) here before.

kind regards,

I saw the thread, but I didn't see how it was solved. There were still errors.

Oh boo hoo!

Nobody posted perfect code that you could copy. I'm sure someone (probably Jos) offered plenty of suggestions and help that would allow you to solve the problem on your own. Any code that was posted might partially solve your problem. It would still be upto you to take that code and rework it so that it did fully solve your problem. Remember it is your work not ours.
