Class Employee Attributes (all private): id: String lastName: String firstName: String salary: int Methods: Parameterized constructor for initializing a new Employee instance Getters for all attributes toString method to display an Employee's attributes (See output of executable below) Executable Class Create an array of at least eight Employee objects. Be sure to use many with identical last names, but don't order them by name in the array. Create an ArrayList from the array. Sort the ArrayList first by last name and then by first name. Using the forEach method and a lambda expression, print all employees alphabetically sorted by name. Create a LinkedList from the ArrayList. Create an iterator capable of cycling both forward and backward through the LinkedList. Iterate forward through the LinkedList without generating any output. Then iterate backwards through the LinkedList to print…Create a class and a main() method that implements the following (define the local variables or additional arrays as you see necessary): USE JAVA LANGUAGE Create a salary array (integer type) with 12 elements. Ask the user to input value from keyboard for each array element. If the input value is not between 0 and 15,000, keep asking the user to re-input till a valid value is obtained (hint: use a while loop). If one’s salary is higher than $8,000, he/she get 8% of his/her salary for bonus. Otherwise the bonus rate is 12%. After the salary information has been input for everyone, print out the salary and bonus for everyone. Each record in a separate line. Find out the highest bonus value and print it out.
