///if the for loop is changed to i<=message.length() the programs stops after listing the characters and displays a an exception message that the String index is out of range
///if the String contains "box" the length is three and the position of the letter "x" is two
/// the for loop repeat as long as i < message.length() instead of i <= message.length() because the value of i as to be less than the message for the characters to be found in a position and if it's equal it doesn't have a position
