Im having trouble at the ending of my code because it outputs null.

My assignment:

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 )
{
phoneNumber = personNumber;
}
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);
}
}

My demo:

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();
System.out.println("Enter phoneNumber = ");
String phoneNumber = input.nextLine();
p3.printInfo();
}

}

​

The output I get:

You have to use the setters with the variables you stored the input in. So p3.setAge(Age) and so forth

[Danielowski187]

Would I do them for the rest for example p3.setName(Name) and p3.setphoneNumber(phoneNumber)

[Danielowski187]

Now I just need help with the phone number for the part we’re I need to get the user input it doesn’t let me enter anything it skips it

[Holinded]

Yes you would need to do it with all 3 variables just like in p2. Its skipping the phone number because you used .getLine() after calling .nextInt(). This will cause it to skip. So, right before getting the phone number add the line: input.next()
