Employee.java
public class Employee
{
    String name; // instance variable
    int age; // instance variable

    static int companyCode = 2000; // static variable

    public int getSalary()
    {
        int salary = 60000; // local variable
        int tax = 10000; // local variable
        salary = salary - tax;
        return salary;
    }

}
EmployeeDemo.java
public class EmployeeDemo
{

    public static void main(String[] args)
    {
        Employee employeeObj = new Employee();
        
        /*
         *  Accessing the instance variable's name and age.
         */
        employeeObj.name = "Peter";
        employeeObj.age = 32;
        
        System.out.println("name : "+employeeObj.name);
        System.out.println("age : "+employeeObj.age);
        

        /*
         *  Accessing the static variable companyCode.
         */
        System.out.println("companyCode : "+Employee.companyCode);
        
        int salary = employeeObj.getSalary();
        System.out.println("salary : "+salary);

    }
