Scanner not storing string as a parsed LocalDateTime correctly

Question

When I am taking in a string variable from the scanner and parsing it to LocalDateTime in the format "yyyy-MM-dd HH:mm" the Scanner saved the input (i.e 2020-10-12 14:30) without the time. I believe the time is being saved into the next variable. However if I input 2020-10-1214:30 without the space, it saves the the variable correctly.

Below is my constructor where the object is being created and the string is being parsed into the localdatetime object.

public computerbooking(String strDAte, String ReturnDate,String computerType,String AssetTag,String StudentId ){
counter++;
this.bookingId  = "Book"+counter;
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm");
bookingDateAndTime = bookingDateAndTime.parse(strDAte,formatter);
returnDateAndTime = returnDateAndTime.parse(ReturnDate,formatter);
this.computerType = computerType;
this.AssetTag = AssetTag;
this.StudentId = StudentId;

}

How do I instruct the scanner not to read the space between the date and time to save it correctly

1. LocalDateTime#parse is a static function. Use LocalDateTime.parse(strDate, formatter) instead of bookingDateAndTime.parse(strDAte,formatter).
2. Use Scanner#nextLine to scan the full line of input. If you are using Scanner#next, it will scan only up to 2020-10-12 i.e. it will stop scanning as soon as it will come across a whitespace character after 2020-10-12.

Demo:

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.util.Scanner;

class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("Enter date and time: ");
        String strDate = scanner.nextLine();

        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("uuuu-MM-dd HH:mm");
        LocalDateTime bookingDateAndTime = LocalDateTime.parse(strDate, formatter);
        System.out.println(bookingDateAndTime);

        // A custom format
        String formatted = bookingDateAndTime.format(DateTimeFormatter.ofPattern("MMM dd uuuu hh:mm a"));
        System.out.println(formatted);
    }
}

A sample run:

Enter date and time: 2020-10-12 14:30
2020-10-12T14:30
Oct 12 2020 02:30 pm
