Employeeclass to store the employee's details:- Name
- ID
- Basic Salary
- Designation
- Department
- Design an
-
Salary Components:
- Add methods to calculate the following components of the salary:
- House Rent Allowance (HRA) = 20% of Basic Salary
- Dearness Allowance (DA) = 10% of Basic Salary
- Provident Fund (PF) = 12% of Basic Salary
- Medical Allowance = Fixed amount (e.g., 1500)
- Gross Salary = Basic Salary + HRA + DA + Medical Allowance
- Net Salary = Gross Salary - PF
- Add methods to calculate the following components of the salary:
-
Input Handling:
- Write a method to take input for employee details and basic salary.
- Ensure the input salary is a positive number.
-
Output Handling:
- Write a method to display the employee details and all components of the salary, including Gross Salary and Net Salary.
