How to print the following output with java?

The system seems to be inconsistent to manage the customer details and address details in the same class. So how it would be if we split the class into two classes called the 'Customer' and 'Address' and just by using both of their  id to uniquely identify each other by placing the customer id in the address class and address id in the customer class so that we can map many addresses with customer and vice versa?

Let us seek how we can do that. First of all the customer details are collected along with the address id and address details are collected along with customer id so that they can be interrelated easily.
Sample Input and Output 1:

Not sure which line is line 63 that is causing the issue, but if it is around here then what name is being entered?

Can you show the output from the app (not just the stack trace)?

I ask because if the name is something like 'John Smith' then Scanner's next() method doesn't do what you expect.

May i know which function of Scanner can help the input like "John Smith"

[Moderation comment] Removed a huge amount of unnecessary quote

The expected result is...
1)Checking Account
2)Saving Account
3)Fixed Account
Enter Account Type
Enter The Account Number
Enter The Customer Name
Enter The Amount
Enter The InterestRate
Hi Jimesh Sharma, currently you are using Saving Account.
Your account number is ACC456753
Your are currently holding amount Rs.65846.0
Rate of interest is 3.0%

I created a code for Inheritance and Encapsulation. It throws error for two testcases and it produces answer for another two. Kindly help me.
import java.io.*; import java.util.*; class Account { public String accountNumber; public double amount; public String customerName; public String getAccountNumber() { return this.accountNumber; } public double getAmount() { return this.amount; } public String getCustomerName() { return this.customerName; } public void setAccountNumber(String newAccNum) { this.accountNumber = newAccNum; } public void setAmount(double newAmount) { this.amount = newAmount; } public void setCustomerName(String newCustomerName) { this.customerName = newCustomerName; } } class SavingsAccount extends Account { public double interestRate; } class FixedAccount extends Account { public int numberOfYears; } class CheckingAccount extends Account { } class Main { public static void main(String[] args) throws IOException { Scanner sc = new Scanner(System.in); Account ac = new Account(); SavingsAccount sa = new SavingsAccount(); FixedAccount fa = new FixedAccount(); CheckingAccount ca = new CheckingAccount(); System.out.println("1)Checking Account"); System.out.println("2)Saving Account"); System.out.println("3)Fixed Account"); System.out.println("Enter Account Type"); int choice = sc.nextInt(); switch (choice) { case 1: { System.out.println("Enter The Account Number"); ac.accountNumber = sc.next(); System.out.println("Enter The Customer Name"); ac.customerName = sc.next(); System.out.println("Enter The Amount"); ac.amount = sc.nextDouble(); System.out.println("Hi " + ac.getCustomerName() + ", " + "currently you are using Checking Account."); System.out.println("Your account number is " + ac.getAccountNumber()); System.out.println("Your are currently holding amount Rs." + ac.getAmount()); break; } case 2: { System.out.println("Enter The Account Number"); ac.accountNumber = sc.next(); System.out.println("Enter The Customer Name"); ac.customerName = sc.next(); System.out.println("Enter The Amount"); ac.amount = sc.nextDouble(); System.out.println("Enter The InterestRate"); sa.interestRate = sc.nextDouble(); System.out.println("Hi " + ac.getCustomerName() + ", " + "currently you are using Savings Account."); System.out.println("Your account number is " + ac.getAccountNumber()); System.out.println("Your are currently holding amount Rs." + ac.getAmount()); System.out.println("Rate of interest is " + sa.interestRate + "%"); break; } case 3: { System.out.println("Enter The Account Number"); ac.accountNumber = sc.next(); System.out.println("Enter The Customer Name"); ac.customerName = sc.next(); System.out.println("Enter The Amount"); ac.amount = sc.nextDouble(); System.out.println("Enter The Number Of Years"); fa.numberOfYears = sc.nextInt(); System.out.println("Hi " + ac.getCustomerName() + ", " + "currently you are using Fixed Account."); System.out.println("Your account number is " + ac.getAccountNumber()); System.out.println("Your are currently holding amount Rs." + ac.getAmount()); System.out.println("Number of years " + fa.numberOfYears); break; } default: System.out.println("Invalid Account Type"); } } }

The error i get is.....
