Deposits in my Bank Account Program

public void deposit(double amount)
{
 balance += amount;
}

This is what I'm calling in another class. I want to be able to deposit 100$ into this account.

Account acct1;

acct1 = new Account(500, "Joe", 1112);

What would I need to do in order to deposit into this account? I've tried different variations of this (below), but I'm confused as to what to do.

initBal = new deposit(100);

Help?

Make sure your Account object stores your initial balance and that your deposit method increase it:

Example:

public class Account{

    private Double balance;

    public Account(Double initBalance, String name, int number){
        this.balance = initBalance;
    }

    public void deposit(double amount)
    {
        balance += amount;
    }

}

Then when you create an instance of Account acct1 = new Account(500, "Joe", 1112);

Then, to increase the balance of your account, you have to call the deposit method that is inside your instance of Account

 acct1.deposit(amount)

The syntax for what it appears you want to do is:

Account acct1;                           //Creating a reference of type Account
acct1 = new Account(500, "Joe", 1112);   //Instantiating a new Account object, 
                                         //giving a reference to that object to acct1
acct1.deposit(100);                      //Calling the deposit method in class Account
                                         //On the object referred to by acct1

More generally, to call a method on an object (of a type that has that method):

<object_reference>.<method_name>(<parameter 1>, <parameter 2>, ...);
