Can this Class be cleaned up at all?

Here's a class I wrote:

package employees;

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;

public class Employee {
    private int employeeNumber;
    private String employeeName;
    private Date hireDate;
    private float initialSalary;
    private String jobTitle;
    public Employee(int employeeNumber, String employeeName, Calendar date,
float initialSalary, String jobTitle) {
        this.employeeNumber = employeeNumber;
        this.employeeName = employeeName;
        this.initialSalary = initialSalary;
        this.jobTitle = jobTitle;
        this.hireDate = date.getTime();
    }
    public Employee(int employeeNumber, String employeeName, Calendar date,
float initialSalary) {
        this.employeeNumber = employeeNumber;
        this.employeeName = employeeName;
        this.initialSalary = initialSalary;
        this.hireDate = date.getTime();
    }

    void displayAll () {
        System.out.println("Employee Information");
        System.out.println("Employee Name: " + employeeName);
        System.out.println("Employee Number: " + employeeNumber);
        System.out.println("Initial Salary: " + initialSalary);
        System.out.println("Job Title: " + jobTitle);
        this.displayHireDate();
    }
    void displayHireDate()
    {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd");
        System.out.println("Hire Date: " + sdf.format(this.hireDate));
    }

    public String getEmployeeName() {
        return employeeName;
    }

    public void setEmployeeName(String employeeName) {
        this.employeeName = employeeName;
    }

    public int getEmployeeNumber() {
        return employeeNumber;
    }

    public void setEmployeeNumber(int employeeNumber) {
        this.employeeNumber = employeeNumber;
    }

    public Date getHireDate() {
        return hireDate;
    }

    public void setHireDate(Calendar c) {
        this.hireDate = c.getTime();
    }

    public float getInitialSalary() {
        return initialSalary;
    }

    public void setInitialSalary(float initialSalary) {
        this.initialSalary = initialSalary;
    }

    public String getJobTitle() {
        return jobTitle;
    }

    public void setJobTitle(String jobTitle) {
        this.jobTitle = jobTitle;
    }
}

Is there anything that can be changed to make it look less clunky? I
was thinking about making it an interface and having it implemented but
when I thought about the IS-A HAS-A guideline I thought it would make
more sense to have the Employee class and an interface called
EmployeeDoes to encapsulate the methods.

Any thoughts?
