Scenario: Developers need to develop a tax calculator for calculating tax using arithmetic, relational and logical operators.
Problem Statement 1: Declaring instance variables.
Develop a class “TaxCalculator” inside a package “com.java2learn.tax”. The class should have an instance float variable named “basicSalary” and a boolean variable named “citizenship”.

Problem Statement 2: Usage of Arithmetic operators.
In the TaxCalculator class create a method named calculateTax() that should calculate and print the tax, the tax should be calculated as follows
tax = 30*basic salary/100
NOTE: The value stored in the instance variable “basicSalary” should be used in the above calculation.
The calculated tax needs to be stored in another instance float variable “tax”.
This method will display the following message in the console.
“The Tax of the employee for the <basic Salary> is <tax>”.
