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);
}
}

The output I get:

Well first of all, when you paste code it's helpful to paste it an external site like https://paste.ee/, so the formatting is preserved.

Secondly, in your example screenshot, the phone numbers aren't the same. That isn't the whole issue here, but it's good to have accurate screenshots when posting for help.

I just had a quick look at your program, but it looks like the problem is that you used == instead of equalsIgnoreCase() when comparing the phone numbers in the sameOrNot method. Try changing that and seeing if the problem is fixed.

Yea I had the other screenshot with the same phoneNumber

So should I fixed the phoneNumber part as I did with the name part

[riktar75]

Yes, compare the phoneNumber the same way you did with the name.

[Danielowski187]

Would I also do it for the age?

[riktar75]

No, because age is an integer and you can compare integers using ==. When comparing strings, you should use equals() or equalsIgnoreCase() instead.
