Project 2

Write a JAVA program to implement bank functionality in the above scenario and demonstrate the OOPs concepts and explain how it is actually satisfying that concept.

Note:

• Create a console application for the banking management system.
• Create few classes namely Customer, Account, RBI (Base Class) and few derived classes (SBI, ICICI, PNB etc). Assume and implement required member variables and functions in each class.
• In every Bank there should be at least 2 types of account saving and current.
• Saving should give simple interest and Current should provide compound interest on deposited amount.
• In the current account the interest is compounded twice a year (on half yearly its compounded).
• For Every type of account at least 2 users will be there.
• On the running of the application it should ask which bank we want to access.
• Then what type of account you have.
• And then for which user account we want to access.
• Minimum amount for saving account is 2000/- and for current account is 5000/-
• And we can calculate the interest for any given time and total amount as well.
• Interest rates for saving will be 5% annually and for current it will be 8% annually.
• Before calculating interest it should ask the user for how many years you want to calculate it.
• Write code to calculate both types of interests as well for any of the users.

For total amount on Simple Interest:

A = P(1 + rt)

Where:

A = final Amount

P = initial Principal balance

r = annual interest rate

t = time (in years)

So, Total Interest = (A - P)

For total amount on Compound Interest:

𝐴 = 𝑃(1 + 𝑟

𝑛

)

𝑛𝑡

A = final Amount

P = initial Principal balance

r = annual interest rate

t = time (in years)

n = number of times interest is compounded per year

Sample Input	Sample Output
Want to open an account?	yes/No
If yes, Insert name, type of account and date of birth, in which bank you want	Account has been opened and account no is: 123
Want to print mini statement	If yes, save it in .txt file somewhere
Calculate interest	If yes, calculate and print

Hint:

Class Customer

{

//Personal Details ...

// Few functions ...

}

Class Account

{

// Account Detail ...

// Few functions ...

}

Class RBI

{

Customer c; //hasA relationship

Account a; //hasA relationship

..

Public double GetInterestRate() { }

Public double GetWithdrawalLimit() { }

}

Class SBI: public RBI

{

//Use RBI functionality or define own functionality.

}

Class ICICI: public RBI

{

//Use RBI functionality or define own functionality.

}

Code:

package BankingProject;

import java.util.Scanner;

class BankDetails {
private String accno;
private String name;
private String acc_type;
private long balance;
Scanner sc = new Scanner(System.in);

// method to open new account
public void openAccount() {
System.out.print("Enter Account No: ");
accno = sc.next();
System.out.print("Enter Account type: ");
acc_type = sc.next();
System.out.print("Enter Name: ");
name = sc.next();
System.out.print("Enter Balance: ");
balance = sc.nextLong();
}

// method to display account details
public void showAccount() {
System.out.println("Name of account holder: " + name);
System.out.println("Account no.: " + accno);
System.out.println("Account type: " + acc_type);
System.out.println("Balance: " + balance);
}

// method to deposit money
public void deposit() {
long amt;
System.out.println("Enter the amount you want to deposit: ");
amt = sc.nextLong();
balance = balance + amt;
}

// method to withdraw money
public void withdrawal() {
long amt;
System.out.println("Enter the amount you want to withdraw: ");
amt = sc.nextLong();
if (balance >= amt) {
balance = balance - amt;
System.out.println("Balance after withdrawal: " + balance);
} else {
System.out.println("Your balance is less than " + amt + "\tTransaction failed...!!");
}
}

// method to search an account number
public boolean search(String ac_no) {
if (accno.equals(ac_no)) {
showAccount();
return (true);
}
return (false);
}
}
