Question

All the banks operating in India are controlled by RBI. RBI has set a well defined guideline (e.g. minimum interest rate, minimum balance allowed, maximum withdrawal limit etc) which all banks must follow. For example, suppose RBI has set minimum interest rate applicable to a saving bank account to be 4% annually; however, banks are free to use 4% interest rate or to set any rates above it.

 

 

Write a java program to implement bank functionality in the above scenario. Note: 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.

Answer 1

package bank;
import java.util.Scanner;
class  Customer{
    protected String name, address;
    protected int age;
}
class Account{
    protected String accountType, branchType;
}
class RBI{
    
   public int withLimit, n;
    public double P, r, t, averageAmount, totalAmount;
     void setData(double P, double r, int n, double t){
         this.P = P;
         this.t  =t;
         this.n = n;
         this.r = r;
     }
    int set_withdrawal_limit() {
        String accountType, branchType;
         System.out.println("Enter account type\n");
         Scanner scan = new Scanner(System.in);
         accountType = scan.next();
          System.out.println("Enter branch type\n");
          branchType = scan.next();
       
        if (accountType == "SAVINGS" && branchType == "METRO") {
            withLimit = 5000;
        } else {
            withLimit = 4000;
        }
        return withLimit;
    }


    double setInterestRate() {
        return (P + r) / n * t;
    }


    double setMAB() {
        return (averageAmount + totalAmount) / 31;
    }
};


class SBI extends  RBI {
    double setInterestRate() {
        return P * (1 + r / n) + n * t;
    }
    double set_MAB() {
        return (averageAmount + totalAmount) / 30;
    }
}


public class Bank {


    public static void main(String[] args) {
        RBI r = new RBI();
       
        SBI s = new SBI();
         s.setData(10.433, 7.42, 5, 7);
        System.out.println("The interest rate is: \n"+s.setInterestRate());
    }
    
}
