Please help with writing a class

Question

i need help getting started with this assignment. i haven't done anything with writing classes, so i don't know where to start.
i need to create a bank account class that will keep a name, balance, up to 50 deposits, and up to 50 withdrawls. i need to include 2 arrays for the deposits and withdrawls.
Here's what i know:
I need a constructor that takes zero arguments. This constructor would initialize the numeric value to zero.
I need a 2nd constructor that takes one argument, a name as a String value. This constructor would initialize the numeric value to zero.
I need a 3rd constructor that takes two arguments, a name as a String value and a starting "balance" as a double value

Answer 1

Sorry, I was watching a movie with my wife ...imagine that. Study my examples here and try to understand what I have done. You will follow the same methodology for the rest of the program. Use main to test the methods in your program.
public class mdlAccount {
  String name;
  double balance;
  int currentDeposit = 0;
  int currentWithdrawl = 0;
  double[] deposits = new double[50];
  double[] withdrawals = new double[50];
  public mdlAccount() {
    name = "";
    balance = 0.0;
  public mdlAccount(String name) {
    this.name = name;
    balance = 0.0;
  public mdlAccount(String name, double balance) {
    this.name = name;
    this.balance = balance;
  // When the instructor says: Have a method that does deposits...
  // You need to create a method, similar to the constructors,
  // but with a return value, even if it returns void (nothing).
  // Like this:
  public void deposit( double amount ) {
    // Do some error checking.
    if ( currentDeposit < 50 && amount > 0 ) { // > is a greater than sign
      // If all is ok, add to the balance...
      balance += amount;
      // and add the entry to the array of deposits
      deposits[currentDeposit] = amount;
      // Finally, add 1 to the currentDeposit variable.
      currentDeposit++;
  // We need the 'return the balance' method so we can see if
  // the program runs correctly. This time we return a double,
  // instead of void. (void means don't return anything at all).
  public double getBalance() {
    return balance;
// Now you create the next method for withdrawals...
//  if ( currentWithdrawl < 50 ) {
//    deposits[currentWithdrawl] = amount;
//    currentWithdrawl++;
  // You want a main method so this class can be executed.
  // You can remove it later if you want to use this class
  // from within another larger program.
  public static void main(String[] args) {
    mdlAccount acct = new mdlAccount( "GumB", 100.0 );
    System.out.println("Initial balance is " + acct.getBalance());
    acct.deposit( 50.0 );
    System.out.println("Current balance is " + acct.getBalance());
}
