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.

AIM:

To JAVA program to implement bank functionality in the above scenario and demonstrate the OOPs concepts.

Coding:

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);
}
}
public class BankingApp {
public static void main(String arg[]) {
Scanner sc = new Scanner(System.in);
//create initial accounts
System.out.print("How many number of customers do you want to input? ");
int n = sc.nextInt();
BankDetails C[] = new BankDetails[n];
for (int i = 0; i < C.length; i++) {
C[i] = new BankDetails();
C[i].openAccount();
}
// loop runs until number 5 is not pressed to exit
int ch;
do {
System.out.println("\n ***Banking System Application***");
System.out.println("1. Display all account details \n 2. Search by Account number\n 3. Deposit the amount \n 4. Withdraw the amount \n 5.Exit ");
System.out.println("Enter your choice: ");
ch = sc.nextInt();
switch (ch) {
case 1:
for (int i = 0; i < C.length; i++) {
C[i].showAccount();
}
break;
case 2:
System.out.print("Enter account no. you want to search: ");
String ac_no = sc.next();
boolean found = false;
for (int i = 0; i < C.length; i++) {
found = C[i].search(ac_no);
if (found) {
break;
}
}
if (!found) {
System.out.println("Search failed! Account doesn't exist..!!");
}
break;
case 3:
System.out.print("Enter Account no. : ");
ac_no = sc.next();
found = false;
for (int i = 0; i < C.length; i++) {
found = C[i].search(ac_no);
if (found) {
C[i].deposit();
break;
}
}
if (!found) {
System.out.println("Search failed! Account doesn't exist..!!");
}
break;
case 4:
System.out.print("Enter Account No : ");
ac_no = sc.next();
found = false;
for (int i = 0; i < C.length; i++) {
found = C[i].search(ac_no);
if (found) {
C[i].withdrawal();
break;
}
}
if (!found) {
System.out.println("Search failed! Account doesn't exist..!!");
}
break;
case 5:
System.out.println("See you soon...");
break;
}
}
while (ch != 5);
}
}

RESULT:

Thus the JAVA program to implement bank functionality in the above scenario and demonstrate the OOPs concepts are successfully created and output was verified.
