Implement a Java program for a simple banking system called MyBank. The program should consist of classes representing checking and savings accounts. Each account should have functionalities for deposit, withdrawal, and displaying account information. The main program should provide a menu-driven interface allowing users to open checking and savings accounts, perform transactions (deposit, withdraw), print account information, and calculate monthly interest for savings accounts. Additionally, ensure that the program handles invalid inputs gracefully. The provided code gives you a starting point. Your task is to complete the implementation of the Checkings and Savings classes, and incorporate the necessary methods in the MyBank class to make the banking system fully functional. Pay attention to input validation and ensure that the program provides a user-friendly interface. ANS: import java.util.*; public class MyBank { static Scanner in = new Scanner(System.in); static ArrayList checking = new ArrayList<>(); static ArrayList saving = new ArrayList<>(); public static void main(String[] args) { int id=0; boolean done = false; do { System.out.println("\n**********************************\n"); System.out.println ( "Select an option:"); System.out.println ( "1) Open a checking account" ); System.out.println ( "2) Checking deposit" ); System.out.println ( "3) Checking withdraw" ); System.out.println ( "4) Print checking account info." ); System.out.println ( "5) Open a saving account" ); System.out.println ( "6) Saving deposit." ); System.out.println ( "7) Saving withdraw." ); System.out.println ( "8) Print monthly interest" ); System.out.println ( "9) Print saving account info."); System.out.println ( "10) Exit"); int option; option = in.nextInt();in.nextLine(); System.out.println ( "\n**********************************\n" ); switch (option) { case 1: openChecking(); break; case 2: System.out.print ( "Enter account number: "); id= in.nextInt(); if(id>=1000&&id=1000&&id=1000&&id=1000&&id=1000&&id=1000&&id=1000&&id
