[JAVA rookie] do a book project, a reservation system, encounter bug

The

code is as follows, but it"s not finished yet:

popped up the following error, checked one side of the code, found nothing wrong, where exactly?

Apr.09,2021

The

console says the error code in the 32 lines of code choose = input.nextInt ();
Scanner, and the nextInt method starts

 public String next(Pattern pattern) {
        ensureOpen();
        if (pattern == null)
            throw new NullPointerException();

        // Did we already find this pattern?
        if (hasNextPattern == pattern)
            return getCachedResult();
        clearCaches();

        // Search for the pattern
        while (true) {
            String token = getCompleteTokenInBuffer(pattern);
            if (token != null) {
                matchValid = true;
                skipped = false;
                return token;
            }
            if (needInput)
                readInput();
            else
                throwFor();//
        }
    }

InputMismatchException exception, which is thrown if the next tag does not match the Integer regular expression or is out of range. The first time you want to enter an integer is 1-6.


I know what the problem is. When entering the bug, of eclipse itself, move the cursor after the colon
