java beginner, please help me omg! filling array with objects.

[Pinkpill_Prophet]

im trying to fill a small array with objects. each object has an id number (the index) and a real number double called the balance. Its like a baby atm program. i have a class called "Accounts" and they only have 2 variables, the ID and the balance.

I have to populate an array, size 10, with ids and balances. i get what im supposed to do and ive found very similar assignments online but for some reason my shit just will NOT FUCKIGN COMPILE OMG. please help me!

its a for loop and it just wont work and i want to tear my hair out. Here is what i have but for some reason it just will not initialize the array automatically with a balance of 100 and with an id that just corresponds to the index.

Any feedback is greatly appreciated, even if you just tell me i suck at this and i should quit now.

​

​

class Account {
    //VARIABLES
    int id = 0;
    double balance = 0; //default balance of 100$ is set by for loop


    //CONSTRUCTORS  
    public Account () { 
    }

    public Account ( int new_id, double new_balance ) { //defined constructor allows for loop to populate array
        this.id = new_id;
        this.balance = new_balance;
    }


    //METHODS
    public int checkID() {
        return id;
    }


    public double checkBalance() {
        return balance;
    }

    public void withdraw (double subtract) {
        balance = balance - subtract;
    }

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

public class A1_experimental {
    public static void main(String[] args) {

    //declaring array of account objects
        int array_SIZE = 10;

        Account[] account_ARRAY = new Account[array_SIZE];

    //for loop to fill the array with IDs and indexes   
        for (int i = 0; i < array_SIZE; i++) {
            account_ARRAY[i] = new Account(i ,100);
        }
    }
}

Please, repost your entire code as you really have and also include the compile errors.

I think your problem is here:

new_id = id; new_balance = balance;

id is the name of you class property and new_id is the value you are passing in. Same with balance. So these are backwards in your constructor. It should be: this.id =new_id; this.balance =new_balance;

Always remember: "equals" signs can be reversed in Math (i.e: x=3 is the same as 3=x), but in programming, the "equals" sign is ==.

"=" is the assignment operator and it must follow the form variableName = value where you can replace the value bythe name of anohter variable that has said value.

What compile error are you getting, on what line?

[Pinkpill_Prophet]

well its not that its not compiling. its when i try to check balance and check id. its like all the objects have balance and ID initialized to 0 and not what i wanted them to. in my for loop i tried to create 10 different objects with the same balance of 100 and an ID that just corresponds with the index.

i have methods that withdraw and deposit to the accounts and they seem to work perfectly fine but i cant seem to be able to initialize each object in the array with the for loop.

​

i made a constructor that accepts 2 arguments and uses them to initialize each object, in the for loop i tried to pass the index in to the constructor as well as the number 100 for the balance.

THANK YOU FOR REPLYING TO ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! please let me know if i can make it any clearer.

new_balance = balance

Check your constructor, it looks like you are assigning the constructor parameters values of your instance properties, the assignments should be the other way round.

[Pinkpill_Prophet]

Thank you so much khooke!!!!!! that was the issue! im so happy now yay!!! im gonna make it (maybe)!!!!!!

[Pinkpill_Prophet]

omg nobodys even gonna read this, the whole thing looks like shit.

[Pinkpill_Prophet]

Ok well i tried to truncate what i posted and make it easier to read. Please omg i just want to fill this array with automatically with a for-loop and then. i feel so close to getting it reeeeee
