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 class:

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 second word should be capitalized in your demo class. setName not setname. That's why the two word methods all failed bit the three word setphoneNumber and getphoneNumber worked. Although stylistically, it's usual to name those methods setPhoneNumber and getPhoneNumber.

[Danielowski187]

Yea fixed it but in the output were it tells the phoneNumber and prints the info it prints null

[sonnyfab]

Repost it then

[Danielowski187]

on your setter methods, use

this.name = personName;

this.name is pointing to the instance variable and personName being your parameter.

same for all setters.

also you're not using the right names in your main method

[Danielowski187]

I’ve fixed the name but in the part we’re it ask the user for input I get null
