1999 Exercise 4: (2 points) Project Name Instruction : _LABO5_BankAccount : Download BankAccount.java from Google Classroom and complete a BankAccount class in the following tasks. a) Create a Developer package and put BankAccount.java in this package. Put appropriate keywords and visibility modifiers (static, private, and public) in the program below so that it fulfils the following requirements. 1. numAccount keeps the number of BankAccount objects that has been created. The numAccount must be accessible anywhere. 2. owner Name, and balance variables can only be accessed inside of the BankAccount class, but not anywhere else. 3. account Number can only be accessed inside of the package Developer, but not anywhere else. 4. deposit methods must be accessible anywhere, and withdraw methods can only be accessed from any class on the same package or outside of the package for its subclass 5. printInfo method can only be accessed inside of the BankAccount class and within the package Developer, but not anywhere else. package Developer; public class BankAccount { // String ownerName; 11 account Number; double balance; // int numAccount; 17 balance) { BankAccount(String owner Name, String accountNumber, double this.ownerName = ownerName; this.accountNumber = account Number; this.balance = balance; numAccount++; 3 void deposit (double amount) { balance - balance + amount; System.out.println("Deposit: $"+amount); 3 void withdraw(double amount) { if (balance > amount) { balance = balance - amount; System.out.println("Withdraw: $"+amount): }else { System.out.println("Not enough balancel"); } ) 3 2. Exercise 5: (2 points) Project Name Instruction : _LABO5_BankAccount : Download BankAccount01_Testing.java and BankAccount02_Testing java from Google Classroom and complete the following tasks. a) Put BankAccount.java in the Developer package, and answer in the following questions: Exercise 5-a-1 and Exercise 5-a-2. package Developer; public class BankAccounti_Testing public static void main(String[] args) { BankAccount account1 = new BankAccount ("Paris Hilton", "127-983-3847", 1000eee.ee); 1/System.out.println("The balance of accounti is $" + account1.balance); //deposit $300 for accounti //print out the balance of accounti Exercise 5-a-1 //System.out.println("The balance of accounti is $" + accounti.balance); Uncomment the above code and run this Java project.
