public class PrimeNumber{ public Boolean validate(final Integer primeNumber) { for (int i = 2; i < (primeNumber / 2); i++) { if (primeNumber % i == 0) { return false; } } return true; } }

Consider the above class "PrimeNumber" and run the test cases. Perform the following task.

a) invoke the class using "@RunWith" to run the tests in that class.

b) Send at least 4 parameters to check if these are prime or not.

c) Create a test runner to perform the functional tests. It further notifies failure or successful results. (Use main() for command-line execution)
