Question

There are two kinds of bank accounts: checking and savings. You can deposit to (i.e. add money in) or withdraw (i.e. take money out) from an account. A checking account can be withdrawn with an unlimited number of times. A savings account can only be withdrawn at most N times per calendar month. Checking accounts have no monthly fee. Savings accounts have a fixed monthly fee X. But if you deposit at least a money amount of M each month, that fee is waived. You cannot overdraft (take out more money than the current balance) a savings account. For a checking account, if you overdraft, you will have to pay an overdraft fee. 1. Design 3 classes: Account, CheckingAccount, and SavingsAccount 2. Determine the fields and methods of each class. 3. Implement the methods to deposit and withdraw. Please use java for the code.

Answer 1

// file name Account.java

//Run the code once you will understand the flow
import java.io.*;
import java.util.Scanner;
public class Account{
//Assuming that fee is 50 and it will be waived of when he do two deposits in a month
static int amount=1000,fee=50,money=2000,free=5;
// amount is used as base amount, money is the amount which is tha base amount for waivering of the transaction fee
static int c=0;
// c is used to continue the loop
   public static void main (String[] args) {
   int a,b;
   while(c==0){
   System.out.println("please select type of 1 CheckingAcount 2 SavingsAccount 3 exit");
// select the type of account
   Scanner scanner=new Scanner(System.in);
   a=scanner.nextInt();
   if(a==1){
   CheckingAccount check=new CheckingAccount();
   System.out.println("Please select action 1.Withdraw 2. deposit 3.exit");
   //selection of operation
   b=scanner.nextInt();
   if(b==2){
   check.deposit();
   }
   else if (b==1){
   check.withdraw();
   }
   else if(b==3){
   c=1;
   // to exit from the transaction
   System.out.println("Thank you");
   }
   else{

   }
