Thread: Problem with OOP - Inheritance

Basically I've made 4 classes, 1 main class, which 3 classes are then extended by. This is the main class file:

public class Account
{   
     private float balance;
 
    float getBalance()
    {
        return balance;
    }   
 
}

A class file that extends on this is:

public class Second extends Account
{
 
     private float balance;
 
    public Loan(float loanBalance)
    {
        balance = loanBalance;
    }
 
}

My main class file is:

public class Main {
 
    public static void main(String[] args)
    {
       Second JoeLoan = new Second(2000);
       float f = JoeLoan.getBalance();
      System.out.println(f);
    }
}

This should ideally output 2000.0, however it outputs 0.0... any idea what could be wrong?
