An example of a display method for an attribute is writeOutName(): void, in which you just display the name:System.out.println("Employee Name: " + name); An equals method that has an object of type Employee as argument, and returns true if two employees have the same name, salary, and SSN. Write a driver program for the Employee class that uses an array that can hold up to 100 employees (the array will be of EmployeeException type). However, the user should be free to enter as many employees as needed. The driver class should use two exception classes to signal the user that the SSN entered is not correct.…arrow_forwardDesign a class named Author with the following members: A field for the author’s name (a String) A field for the author’s year of birth (an int) One or more constructors and appropriate accessor and mutator methods A toString method that displays the author’s info as: Author: Mary Shelley (1797) Save the file as Author.java.
