We are interested in testing the performance of the static class EMath with the following public interface;

+ gcd(String x. String y): int, NumberFormatException

+ absolute(String x): int NumberFormatException

+ module(String x, Suing y ): int ArithmeticException, NumberFormatException

Where the member methods of the class;

gcd(x, y) returns the greatest common divisor of the integer numbers x and y, or exception.

absolute(x) returns the absolute value of x, or exception.

modulo(x, y) returns x modulus y, or exception.

Develop a bank of test using the tools NetBeans and JUnit for testing the right performance of Java objects of the class EMath.
