The ExceptionLab class provided: – Creates an array of 100
elements and fills it with random numbers from 1 to 100. – It asks
the user for an index value between 0 and 99. – Prints the element
at that position. – If a number > 99 is entered by the user, the
class will abort with an ArrayIndexOutOfBoundsException • Modify
