Question

I need to update the code listed below to meet the criteria listed on the bottom. I worked on it a little bit but I could still use some help/corrections!

	import java.util.Scanner;
	public class BankAccount {
	private int accountNo;
	private double balance;
	private String lastName;
	private String firstName;
	public BankAccount(String lname, String fname, int acctNo) {
	lastName = lname;
	firstName = fname;
	accountNo = acctNo;
	balance = 0.0;
	}
	public void deposit(int acctNo, double amount) { // This method is to check that account number is valid, and amount if positive before performing deposit
	balance = balance + amount;
	}
	public void withdraw(int acctNo, double amount) { //This method should check that account number is valid, and balance in account before performing withdrawl
	balance = balance - amount;
	}
	public double getBalance() {
	return balance;
	}
	public String getLastName() {
	return lastName;
	}
	public String getFirstName() {
	return firstName;
	}
	public int getAcctNo() {
	return accountNo;
	}
	public static void main (String [] args) {
	String last, first; //name and account number for new object
	int acct;
	Scanner in = new Scanner(System.in); //create Scanner for input
	BankAccount one;
	// create bank account object
	System.out.println("Enter last name");
	last = in.nextLine();
	System.out.println("Enter first name");
	first = in.nextLine();
	System.out.println("Enter account number");
	acct = in.nextInt();
	one = new BankAccount(last, first, acct);
	/* PRINTS OUT THE INFORMATION IN both objects */
	System.out.println( BankAccount );
	/* ALLOWS THE USER TO enter an account number, and an ammount to deposit */
	public void deposit(double depositAmount)
	{
	balance += depositAmount;
	}
	System.out.println("Enter account number");
	acct = in.nextInt();
	System.out.println("Enter deposit ammount");
	depositAmount = in.nextDouble();
	/* ALLOWS THE USER TO enter an account number, and an amount to withdraw */
	public boolean withdraw(double withdrawAmount)
	{
	if (withdrawAmount > balance){
	System.out.println("Insufficient Funds!!!");
	return false;
	} else {
	balance -= withdrawAmount;
	return true;
	}
	}
	System.out.println("Enter account number");
	acct = in.nextInt();
	System.out.println("Enter withdrawal ammount");
	withdrawAmount = in.nextDouble();
	/* PRINTS OUT THE INFORMATION IN both objects */
	System.out.println( acct , depositAmount );
	System.out.println( acct , withdrawAmount );
	}
	}

* bank deposits should only be performed if the account number is accurate and the amount is positive, otherwise an error message should be given

* bank withdrawls should only be performed if the account number is accurate and the account contains enough money to handle the amount of money withdrawn, otherwise an error message should be given
