Java program for banking management system
In this java program, we will learn how to create a small project like banking system? In this program, we are using some of the banking related options like deposit, withdrawal etc.
Submitted by IncludeHelp, on October 28, 2017
This java program has following main menus:
- Display All
- Search By Account
- Deposit
- Withdrawal
- Exit
Initially, we will add some (N) customers to the bank and then we can display all account details using menu 1), menu 2) is used to search the bank account, menu 3) is used to deposit money in particular account, menu 4) is used to manager withdrawal and menu 5) is used to exit from the program.
Program
import java.util.Scanner;
class Bank {
private String accno;
private String name;
private long balance;
Scanner KB = new Scanner(System.in);
//method to open an account
void openAccount() {
System.out.print("Enter Account No: ");
accno = KB.next();
System.out.print("Enter Name: ");
name = KB.next();
System.out.print("Enter Balance: ");
balance = KB.nextLong();
}
//method to display account details
void showAccount() {
System.out.println(accno + "," + name + "," + balance);
}
//method to deposit money
void deposit() {
long amt;
System.out.println("Enter Amount U Want to Deposit : ");
amt = KB.nextLong();
balance = balance + amt;
}
//method to withdraw money
void withdrawal() {
long amt;
System.out.println("Enter Amount U Want to withdraw : ");
amt = KB.nextLong();
if (balance >= amt) {
balance = balance - amt;
} else {
System.out.println("Less Balance..Transaction Failed..");
}
}
//method to search an account number
boolean search(String acn) {
if (accno.equals(acn)) {
showAccount();
return (true);
}

}
}

System.out.print("How Many Customer U Want to Input : ");
int n = KB.nextInt();
