Java 8.25 lab: contact list a contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. write a program that first takes as input an integer n that represents the number of word pairs in the list to follow. word pairs consist of a name and a phone number (both strings). that list is followed by a name, and your program should output the phone number associated with that name. assume that the list will always contain less than 20 word pairs.

Write a program that uses a random number generator to generate a two digit positive integer and allows the user to perform one or more of the following operations: a. double the number. b. reverse the digits of the number. c. raise the number to the power of 2, 3, or 4. d. sum the digits of the number. e. if the number is a two-digit number, then raise the first digit to the power of the second digit. f. if the number is a three-digit number and the last digit is less than or equal to 4, then raise the first two digits to the power of the last digit. after performing an operation if the number is less than 10, add 10 to the number. also, after each operation determine if the number is prime. each successive operation should be performed on the number generated by the last operation. your program should not contain any global variables and each of these operations must be implemented by a separate function. also, your program should be menu driven. 7.
