I have been trying to execute this code, but despite there being no errors in the actual code, I am getting a NoSuchElementException for it. It's pointing me to a line where I can't understand what is wrong.

Exception in thread "main" java.util.NoSuchElementException
    at java.base/java.util.Scanner.throwFor(Scanner.java:937)
    at java.base/java.util.Scanner.next(Scanner.java:1594)
    at java.base/java.util.Scanner.nextInt(Scanner.java:2258)
    at java.base/java.util.Scanner.nextInt(Scanner.java:2212)
    at assignment8/assignment8.BankAcc.main(BankAcc.java:79)

This is the error it's giving.

I also checked all the suggestions from this link: Java NoSuchElementException But I am still getting the same errors.
