Inputting parameters into an array of objects?

I am trying to input values inside of an array of objects, but I cant seem to get it to work. Essentially, I just need to create an array of accounts that can withdraw and deposit money. I tried going to my professor for help and she said that I just need to initialize the values, since they are all at null initially. However, I am unsure of the syntax for this and my book has similar ways, but not exact. Could anyone help me with this?

import java.util.Scanner;
import java.text.NumberFormat;
public class AccountMain
{
  public static void main(String[] args)
  {
    Scanner scan = new Scanner(System.in);
    Account[] acct = new Account[30];
    for (int count = 0; count < 30; count++)
    {
      acct[count] = new Account("", 0, 0);
    }
                                                                                //creates accounts
    acct[0].Account("Jerry Longhorn", 1, 50.50);
    acct[1].Account("Jimmy Longhorn", 2, 700.20);
    acct[2].Account("Jenny Longhorn", 3, 10000.50);
    acct[3].Account("Jeffrey Longhorn", 4, 400.20);
    acct[4].Account("Jack Longhorn", 5, 500.20);

                                                                                //Determines withdraw or deposit
    System.out.println("Please enter your account number: ");
    int num = scan.nextInt();
    System.out.println("Enter W for withdrawl; D for deposit: ");
    char choice = scan.next().charAt(0);

    if (choice == 'W' || choice == 'w' || choice == 'D' || choice == 'd')
    {

      if (choice == 'W' || choice == 'w')
      {
        System.out.println("Enter amount to withdraw: ");
        double WithdrawMoney = scan.nextDouble();
        acct[--num].withdraw(WithdrawMoney);                                    //MUST --num in order to account for 0
        System.out.println("User # " + num + " funds after withdraw: " + acct[--num].getBalance() + "$");
        System.out.println("User # " + num + " funds after interest: " + acct[--num].addInterest() + "$");
      }
      if (choice == 'D' || choice == 'd')
      {
        System.out.println("Enter amount to deposit: ");
        double DepositMoney = scan.nextDouble();
        acct[--num].deposite(DepositMoney);                                    //MUST --num in order to account for 0
        System.out.println("User # " + num + " funds after deposit: " + acct[--num].getBalance() + "$");
        System.out.println("User # " + num + " funds after interest: " + acct[--num].addInterest() + "$");
      }
      else
        System.out.println("Invalid input.");



    }
  }
}
