  It seems like it's a hexadecimal number

  you're trying to print a complex object, an array, and there's no toString() defined so it prints the default java reference (which is a memory reference a hash)

  to print out the entire array you need to iterate over it yourself.

  try it with a for loop :

  for ( int i; i<arrayMy.length; i++) {
  
        text(arrayMy[i], 30, 18+ 22*i);
  
  }

  If the datatype of your 1D array isn't any of the 8 Java primitives, you can use this utility function makeArrayPrintable() I've made for some old post as a starting point: :\">

  https://Forum.Processing.org/two/discussion/24337/the-table-has-no-column-named#Item_9

  @ SafeVarargs static final String makeArrayPrintable(final Object... arr) {
    if (arr == null || arr.length == 0)  return "";
    final StringBuilder sb = new StringBuilder();
  
    for (final Object obj : arr)  sb.append(obj).append(ENTER);
    return sb.substring(0, sb.length() - 1);
  }
  

  It just needs some extra code for including the index too. #:-S

  In case your 1D array turns out to be 1 of the 8 Java primitives, simply replace each Object in the code above w/ the desired primitive datatype. :ar!

  BtW, makeArrayPrintable() is pretty much similar to join(): :\">

  Of course, makeArrayPrintable() is much more flexible for the datatypes it can accept and potentially more customizable for its output String. \m/
