Here is the piece of code we worked on Tuesday.

Remember that the for loop leaves x as the length of the String (not found) while indexOf() returns -1.

import java.util.Scanner;

public class Main {
  
  static Scanner kb = new Scanner(System.in);

  public static void main(String[] args) {
    int x;
    //                     1
    //           01234567890
    String line="ab,cd,e1,23,45";
    String f, l;
   
    //for ( x = 0; x< line.length() && line.charAt(x) != ',' ; x++);

    // search for comma
    x = line.indexOf(",");
    while ( x != -1 ) {
      // get chunk
      f = line.substring(0,x);
      System.out.println(f);
      //take remainder of string and repeat
      line = line.substring(x+1);
      // search for comma
      x = line.indexOf(",");
    }
    System.out.println(line);
    //System.out.println(x);

/*
    if ( x < line.length()) {

      f = line.substring(0,x);
      l = line.substring(x+1);

      System.out.println(f);
      System.out.println(l);
    } else {
      System.out.println("There is no comma...");
    }
    */
    

  }
}
