Question

you will find a class called Employee. This class should include a constructor that sets name to blanks and salary to $0.00 and a constructor which sets name to a starting name and salary to a set amount. Additionally, the class should include methods to set the name and salary and return the name and salary. Create another method to return the name and salary nicely formatted as a string (hint – research the toString method). You will create a new class called Manager that inherits from the class Employee. Add a field named department of type String. Supply a method toString that prints the manager's name, department, and salary. Remember, you may not change anything in the Employee class. You will then create a test class that uses the Manager class. The test class should prompt the user to enter the name, department, and salary. This information should be stored in an array. Upon entry of 3 employee records, the program should output the information you entered. Your program should be able to handle a maximum of 3 entries. You may write the program as a console application or using dialog boxes. Please remember to include the needed comments at the top of your .java file which will identify this assignment. Please refer to Project Format and Grading Policy on the Syllabus regarding programming project expectations for the semester.
