help needed to create a class
i need help to do this exercise..i get errors but i don't have a solution in the book:
Create a class called Employee that includes three instance variablesâ€"a first name (type String), a last name (type String) and a 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 application named EmployeeTest that demonstrates class Employeeâ€™s capabilities. Create two Employee objects and display each objectâ€™s yearly salary. Then give each Employee a 10% raise and display each Employeeâ€™s yearly salary again.
thanks for your help!
