Please do it int java

The program defined in the Trouble.java file randomly crashes with one of three types of exception or runs to completion if no exception occurs. Modify this programs main() method (using exception-handling) so that the program behaves as follows:

* If calling problem() produces an ArrayIndexOutOfBoundsException, print "Alpha".

* If calling problem() produces a NullPointerException, print "Beta". * If calling problem() produces an ArithmeticException, print "Gamma". * Otherwise, if problem() does not produce any type of exception, print "Delta".

Your program should print exactly one of these four words each time it is executed (e.g., Alpha or Delta, but not Alpha AND Delta). Do not make ANY changes to the problem() method; your solution should ONLY change main() for this exercise.
