I need a Personal Information Class Design a class that holds personal data

Question

more specificly: name, address, age, and phone number. Demonstrate the class by writing a program that creates three instances of it. One instance should hold your information, and the other two should hold your friends’ or family members’ information.

Answer 1

This is an AP Computer Science OOP Class Design. Please see my codes below:

1. Person class to hold person information

public class Person {

/* Fields */

private String name;

private String address;

private int age;

private String phoneNumber;

/* Constructors */

public Person() {

}

public Person(String name, String address, int age, String phoneNumber) {

this.name = name;

this.address = address;

this.age = age;

this.phoneNumber = phoneNumber;

}

/* Getters/Setters */

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getAddress() {

return address;

}

public void setAddress(String address) {

this.address = address;

}

public int getAge() {

return age;

}

public void setAge(int age) {

this.age = age;

}

public String getPhoneNumber() {

return phoneNumber;

}

public void setPhoneNumber(String phoneNumber) {

this.phoneNumber = phoneNumber;

}

@Override

public String toString() {

return String.format("Person: name='%s', address='%s', age=%d, phoneNumber='%s'",

this.name, this.address, this.age, this.phoneNumber);

}

}

1. PersonTest class to test Person class

public class PersonTest {

public static void main(String[] args) {

// Person to hold my information

Person myInfo = new Person("Loc Ha", "Lincoln Nebraska", 41, "402-000-0000");

// My son does not have a phone number

Person mySon = new Person("Leo Ha", "Lincoln Nebraska", 4, null);

// My friend

Person myFriend = new Person("Long Vu", "Denver Colorado ", 41, "720-000-0000");

// Person: name='Loc Ha', address='Lincoln Nebraska', age=41, phoneNumber='402-000-0000'

System.out.println(myInfo);

// Person: name='Leo Ha', address='Lincoln Nebraska', age=4, phoneNumber='null'

System.out.println(mySon);

// Person: name='Long Vu', address='Denver Colorado ', age=41, phoneNumber='720-000-0000'

System.out.println(myFriend);

}

}
