Java: Create Employee class with years of service calculation

Java OOP: Exercise-9 with Solution

Write a Java program to create a class called "Employee" with a name, salary, and hire date attributes, and a method to calculate years of service.

Sample Solution:

Java Code:

// Employee.java
import java.time.LocalDate;
import java.time.Period;

public class Employee {
  private String name;
  private double salary;
  private LocalDate hireDate;

  public Employee(String name, double salary, LocalDate hireDate) {
    this.name = name;
    this.salary = salary;
    this.hireDate = hireDate;
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }

  public double getSalary() {
    return salary;
  }

  public void setSalary(double salary) {
    this.salary = salary;
  }

  public LocalDate getHireDate() {
    return hireDate;
  }

  public void setHireDate(LocalDate hireDate) {
    this.hireDate = hireDate;
  }

  public int getYearsOfService() {
    return Period.between(hireDate, LocalDate.now()).getYears();
  }

  public void printEmployeeDetails() {
    System.out.println("\nName: " + name);
    System.out.println("Salary: " + salary);
    System.out.println("HireDate: " + hireDate);
  }

}

In the above Employee class, there are three private attributes: name, salary, and hireDate, a constructor that initializes these attributes with the values passed as arguments, and getter and setter methods to access and modify these attributes.

There is a method “getYearsOfService()” to calculate years of service between the hire date and the current date, and returns the number of years as an integer value.

//Main.java
import java.time.LocalDate;

public class Main {
  public static void main(String[] args) {
    Employee employee1 = new Employee("Roberta Petrus", 50000, LocalDate.parse("2021-04-01"));
    Employee employee2 = new Employee("Loyd Blair", 70000, LocalDate.parse("2015-04-01"));
    Employee employee3 = new Employee("Magdalena Artemon", 50000, LocalDate.parse("2011-01-15"));
    employee1.printEmployeeDetails();
    System.out.println("Years of Service: " + employee1.getYearsOfService());
    employee2.printEmployeeDetails();
    System.out.println("Years of Service: " + employee2.getYearsOfService());
    employee3.printEmployeeDetails();
    System.out.println("Years of Service: " + employee3.getYearsOfService());
  }
}

In the above main() function, we create three instances of the "Employee" class, and print their name, salary, hire date, and years of service using the appropriate methods.

Sample Output:

Name: Roberta Petrus
Salary: 50000.0
HireDate: 2021-04-01
Years of Service: 2

Name: Loyd Blair
Salary: 70000.0
HireDate: 2015-04-01
Years of Service: 8

Name: Magdalena Artemon
Salary: 50000.0
HireDate: 2011-01-15
Years of Service: 12
