Thank you. But now, when I test the class with the program, it doen't return the correct number of accounts. Each time, it says "0". why?...
CODE
//*******************************************************
// Account.java
//
// A bank account class with methods to deposit to, withdraw from,
// change the name on, and get a String representation
// of the account.
//*******************************************************
public class Account
{
private static int numAccounts = 0;
private double balance;
private String name;
private long acctNum;
//----------------------------------------------
//Constructor -- initializes balance, owner, and account number
//----------------------------------------------
public Account(double initBal, String owner, long number)
{
balance = initBal;
name = owner;
acctNum = number;
}
//----------------------------------------------
// Checks to see if balance is sufficient for withdrawal.
// If so, decrements balance by amount; if not, prints message.
//----------------------------------------------
public void withdraw(double amount)
{
if (balance >= amount)
balance -= amount;
else
System.out.println("Insufficient funds");
}
//----------------------------------------------
// Adds deposit amount to balance.
//----------------------------------------------
public void deposit(double amount)
{
balance += amount;
}
//----------------------------------------------
// Returns balance.
//----------------------------------------------
public double getBalance()
{
return balance;
}
//----------------------------------------------
// Returns account number.
//----------------------------------------------
public long getAcctNumber()
{
return acctNum;
}
//----------------------------------------------
// Returns a string containing the name, account number, and balance.
//----------------------------------------------
public String toString()
{
return "Name: " + name +
"\nAccount Number: " + acctNum +
"\nBalance: " + balance;
}
private static int numAccounts()
{
numAccounts++;
return numAccounts;
}
public static int getnumAccounts()
{
return numAccounts;
}
}]
program:
CODE
//***********************************************************
// TestAccounts1
// A simple program to test the numAccts method of the
// Account class.
//***********************************************************
import java.util.Scanner;
public class TestAccounts1
{
public static void main(String[] args)
{
Account testAcct;
Scanner scan = new Scanner(System.in);
System.out.println("How many accounts would you like to create?");
int num = scan.nextInt();
for (int i=1; i<=num; i++)
{
testAcct = new Account(100, "Name", i);
System.out.println("\nCreated account " + testAcct);
System.out.println("Now there are " + Account.getnumAccounts() +
" accounts");
}
}
}
