Question

JAVA

Create a Java project to implement a simple Name class. This class will have the following class variable:

1. First Name,
2. Middle Name,
3. Last Name, and
4. Full Name

Create the accessor/getter and mutator/setter methods. In addition to these methods, create a toString() method, which overrides the object class toString() method. This override method prints the current value of any of this class object.

Create a main() method to test your project.

Answer 1

public class Name
{
  String firstName, lastName, middleName, fullName;

  public Name(String firstName, String lastName, String middleName) {
    this.firstName = firstName;
    this.lastName = lastName;
    this.middleName = middleName;
    this.fullName = firstName +" "+middleName+" "+lastName;
  }

  public String getFirstName() {
    return firstName;
  }

  public void setFirstName(String firstName) {
    this.firstName = firstName;
  }

  public String getLastName() {
    return lastName;
  }

  public void setLastName(String lastName) {
    this.lastName = lastName;
  }

  public String getMiddleName() {
    return middleName;
  }

  public void setMiddleName(String middleName) {
    this.middleName = middleName;
  }

  public String getFullName() {
    return fullName;
  }

  public void setFullName(String fullName) {
    this.fullName = fullName;
  }

  public String toString() {
    return "Name{" +
            "fullName='" + fullName + '\'' +
            '}';
  }

  public static void main(String[] args) {
    Name obj = new Name("MyFirstName","MyMiddleName","MyLastName");
    System.out.println(obj.firstName);
    System.out.println(obj.middleName);
    System.out.println(obj.lastName);
    System.out.println(obj);
  }
}
