6 (Optional). Define a class TestDivisionException, the requirements are as follows
(1) Define the static method divisionNum, receive two input integers, return the divisible result, and use throws to throw an ArithmeticException exception; (
2) The main method receives keyboard input two Integers a, b; call the divisionNum method, and store the result in the variable c,
(3) If the divisor is 0, catch the exception;
(4) Print out the error message and error stack information;
(5) Finally, whether there is an error or not Print out the result of c, and print "computed".
