1. a). Write a method called generate() that will generate and return an eight digits integer random number. b). Write a method called check() that is passed with eight digits integer random number as an argument to check and return true if the given random number is multiples of 4, otherwise return false. c). Write a main() method to call and execute the generate() method for 10 times and then pass this eight digits integer number to check() method for 10 times and display the result.
