Create a class named Employee that includes three private instance variables, first name (String), last name (String), and monthly salary (double). Provide a constructor that initializes the three instance variables. Provide a set and a get method for each instance variable. If the monthly salary is not positive, do not set its value. Write a test app named EmployeeTest that demonstrates the class Employee’s capabilities. Create two Employee objects and display each object’s yearly salary. Then give each Employee a
20% raise and display each Employee’s yearly salary again.
Use the data below to create the two Employee objects:
First Name Last Name Monthly Salary
John Doe 2875.00
Jane Doe 3150.75
