Need help with this project and not able to complete. Listed complete details below. Thanks!
Bank Account Class
In this program we simulate small part of an account in a bank. The class has the following private
instance data members, which are all declared private. Their description, data types, and suggested
names for them are also given.
Instance data member
Description
Instance data member data type Suggested variable name
Account number associated withthe bank account =integer ActNum
Last Name of the account holder = String LastName
First Name of the account holder = String FirstName
Current Balance in dollars in theaccount =double balance
Table 1
Proceed in the following manner to code either using textpad or Eclipse.
1. Generate a Java class called BankAccount.
2. Add the data members (all private) described in the table 1 to the class.
3. Write an explicit constructor, in above class, which takes four arguments, each one of which
maps to the four class instance data members. The suggested header (first line) for the
constructor is shown.
public BankAccount(int act, String first, String last, double bal)
{
//body of explicit constructor
}
4. Write a print method in class BankAccount whose suggested header is given below.
public void print()
{
Class member ActNum willbe equal to act Class member
FirstName will be equalto first.
Class member LastName will beequal to last
Class member balance willbe equal to bal.
//body of print method
}
This method prints all class data member values to console. Use printf for currency formatting
and output to console.
5. Write another class (suggested name: MainClass), and write a main method in it.
6. In main method call the explicit constructor you wrote in step 3 and pass some hard coded
values as arguments to this constructor. This way you are creating an object of type
BankAccount in your main method. Suggested values for example are as follows:
Account number: 5623
First Name: Jim
Last Name: Jones
Balance: 100.89
7. Call the print method for the BankAccount object you created in step 6 which when you run the
program would print same values that you passed to explicit constructor as arguments. This will
confirm that your explicit constructor is working correctly. If not then fix all errors at this point.
8. Back to the BankAccount class: Now write a method called deposit which simulates depositing
money in a bank account. Deposit method will take a double type argument which is the
amount of money customer wishes to deposit to their current account. Thus after deposit
method is executed the customer
Explanation / Answer
Please find below the program. public class BankAccount { Integer actNum; String lastName; String firstName; double balance; public Integer getActNum() { return actNum; } public BankAccount(Integer actNum, String lastName, String firstName, double balance) { super(); this.actNum = actNum; this.lastName = lastName; this.firstName = firstName; this.balance = balance; } public void setActNum(Integer actNum) { this.actNum = actNum; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public double getBalance() { return balance; } public void setBalance(double balance) { this.balance = balance; } public void print() { System.out.println("Account Number: " + this.actNum); System.out.println("First Name: " + this.firstName); System.out.println("Last Name: " + this.lastName); System.out.println("Balance: " + this.balance); } public void deposit(double money) { this.setBalance(this.getBalance() + money); } public void withdrawal(double money) { if (money > this.getBalance()) System.out.println("Insufficient funds"); else this.setBalance(this.getBalance() - money); } } import java.util.Scanner; public class MainClass { public static void main(String[] args) { BankAccount ba = new BankAccount(5623, "Jim", "Jones", 100.89); ba.print(); System.out.println("How much Amount need to be deposited?"); Scanner sc = new Scanner(System.in); ba.deposit(sc.nextDouble()); System.out.println("Details after depositing"); ba.print(); System.out.println("How much Amount need to be withdrawn?"); ba.withdrawal(sc.nextDouble()); System.out.println("Details after withdrawing"); ba.print(); } } Output: Account Number: 5623 First Name: Jones Last Name: Jim Balance: 100.89 How much Amount need to be deposited? 20 Details after depositing Account Number: 5623 First Name: Jones Last Name: Jim Balance: 120.89 How much Amount need to be withdrawn? 30 Details after withdrawing Account Number: 5623 First Name: Jones Last Name: Jim Balance: 90.89 import java.io.FileWriter; import java.util.Scanner; public class ClientMainClass { public static void main(String[] args) throws Exception { BankAccount ba = new BankAccount(5623, "Jim", "Jones", 100.89); Scanner sc = new Scanner(System.in); System.out.println("Select a Menu Item"); System.out .println("1.
