Question

Write a program that models an employee. An employee has an employee number, a name, an address, and a hire date. A name consists of a first name and a last name. An address consists of a street, a city, a state (2 characters), and a 5-digit zip code. A date consists of an integer month, day and year. All fields are required to be non-blank. The Date fields should be reasonably valid values (ex. month 1-12, day 1-31, year > 1900 and < 2020). Issue appropriate error messages when incorrect data is entered. Create an Employee, a Name, an Address, and a Date classes in your solution. You may use the Date class from the lectures or define your own. The Java-supplied Date class cannot be used. Provide appropriate class constructors, getter methods, setter methods, toString() and any other methods you think are necessary. To keep things simple, your classes don’t need to do any editing of data. The classes should not do any direct user input/output. All user input/output will be done in the main method. Your program should prompt the user to enter data for several employees,store the data in an array of type Employee, and then display the data. Be sure to comment your code and use the course code formatting style.

Explanation / Answer

MyDate.java

public class MyDate {
//Declaring instance variables
private int year;
private int month;
private int day;

//Parameterized constructor
public MyDate(int year, int month, int day) {
super();
this.year = year;
this.month = month;
this.day = day;
}

//getters and setters
public int getYear() {
return year;
}

public void setYear(int year) {
this.year = year;
}

public int getMonth() {
return month;
}

public void setMonth(int month) {
this.month = month;
}

public int getDay() {
return day;
}

public void setDay(int day) {
this.day = day;
}

@Override
public String toString() {
return month + "/" + year + "/" + day;
}

}

Employee.java

public class Employee {

// Declaring variables
private int employeeNumber;
private String name;
private MyDate hireDate;
private String address;

//Parameterized constructor
public Employee(int employeeNumber, String name, MyDate hireDate,
String address) {
super();
this.employeeNumber = employeeNumber;
this.name = name;
this.hireDate = hireDate;
this.address = address;
}

//getters and setters
public int getEmployeeNumber() {
return employeeNumber;
}
public void setEmployeeNumber(int employeeNumber) {
this.employeeNumber = employeeNumber;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public MyDate getHireDate() {
return hireDate;
}
public void setHireDate(MyDate hireDate) {
this.hireDate = hireDate;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}

//toString method is used to display the contents of an object inside it
@Override
public String toString() {
return "Employee Number=" + employeeNumber + " Name=" + name + " Hire Date=" + hireDate + " Address=" + address;
}

}
