Implement a BankAccount that pays a bonus of $10 for each new account.

Complete the following file:

BankAccount.java

/** A bank account has a balance that can be changed by deposits and withdrawals. */ public class BankAccount { private double balance; /** Constructs a bank account with a zero balance. */ public BankAccount() { // your work here balance = ...; } /** Constructs a bank account with a given balance. @param initialBalance the initial balance */ public BankAccount(double initialBalance) { // your work here } /** Deposits money into the bank account. @param amount the amount to deposit */ public void deposit(double amount) { double newBalance = balance + amount; balance = newBalance; } /** Withdraws money from the bank account. @param amount the amount to withdraw */ public void withdraw(double amount) { double newBalance = balance - amount; balance = newBalance; } /** Gets the current balance of the bank account. @return the current balance */ public double getBalance() { return balance; } }

Use the following file:

BankAccountTester.java

public class BankAccountTester   
{
   public static void main(String[] args)
   {
      BankAccount account1 = new BankAccount();
      System.out.println("Balance: " + account1.getBalance());
      System.out.println("Expected: 10");
      BankAccount account2 = new BankAccount(1000);
      System.out.println("Balance: " + account2.getBalance());
      System.out.println("Expected: 1010");      
   }
}
