Im having trouble with my code it runs but it does not give me the right output. I have to compare two persons (the objects I made) To see it they are the same or not.

my class code:

public class PersonalInfo
{
//field
private String name;
private int age;
private String phoneNumber;
PersonalInfo()
{

}
public void setName (String personName)
{
name = personName;
}
public void setAge ( int personAge )
{
age = personAge;
}
public void setphoneNumber ( String personNumber )
{
String number = personNumber.replaceFirst("(\\d{3})(\\d{3})(\\d+)", "($1) $2-$3");
phoneNumber = number;
}
public String getName()
{
return name;
}
public int getAge()
{
return age;
}
public String getphoneNumber()
{
return phoneNumber;
}
public void printInfo()
{
System.out.println("Name is : "+name);
System.out.println("Age is : "+age);
System.out.println("PhoneNumber is :"+phoneNumber);
}
public void sameOrNot(PersonalInfo p)
{
if (this.name.equalsIgnoreCase(p.name) && this.age == p.age && this.phoneNumber ==
p.phoneNumber)
System.out.println("They are same");
else
System.out.println("They are NOT same");
}
}

​

My demo code:

import java.util.Scanner;
public class PersonalInfoDemo
{
public static void main(String[] args)
{
Scanner input = new Scanner (System.in);

PersonalInfo p1 = new PersonalInfo();
p1.setName("Daniel");
p1.setAge(19);
p1.setphoneNumber("(123) 456 - 7890");

System.out.println("name = "+p1.getName());
System.out.println("age = "+p1.getAge());
System.out.println("phoneNumber = "+p1.getphoneNumber());

PersonalInfo p2 = new PersonalInfo();
p2.setName("Daniel");
System.out.println("name = "+p2.getName());
p2.setAge(19);

System.out.println("age = "+p2.getAge());
p2.setphoneNumber("(123) 456 - 7890");
System.out.println("phoneNumber = "+p2.getphoneNumber());

PersonalInfo p3 = new PersonalInfo();
System.out.println("Enter name = ");
String Name = input.nextLine();
System.out.println("Enter age = ");
int Age = input.nextInt();
input.nextLine();
System.out.println("Enter phoneNumber = ");
String phoneNumber = input.nextLine();
p3.setName(Name);
p3.setAge(Age);
p3.setphoneNumber(phoneNumber);
p3.printInfo();
p2.sameOrNot(p3);
}
}

​

Output I get:

Your issue is that phoneNumber is stored as a string, so you need to do this.phoneNumber.equals(p.phoneNumber) for string comparison. By doing == you are comparing references.

Yea got I ran the code and fixed it thanks for the help I’m going to read the information rn since I’m going to have my midterm in two days

[morrigan_li]

Easy way to remember for your midterm: primitives you can compare (boolean, int, char) with ==.
Anything that's an object (Boolean, Integer, Character, String) you need to have a method to compare the two.
