Java Scanner String input

Question

I\'m writing a program that uses an Event class, which has in it an instance of a calendar, and a description of type String. The method to create an event uses a Scanner t

Answer 1

If you use the nextLine() method immediately following the nextInt() method, nextInt() reads integer tokens; because of this, the last newline character for that line of integer input is still queued in the input buffer and the next nextLine() will be reading the remainder of the integer line (which is empty). So we read can read the empty space to another string might work. Check below code.

import java.util.Scanner;

public class Solution {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);

        int i = scan.nextInt();
        Double d = scan.nextDouble();
        String f = scan.nextLine();
        String s = scan.nextLine();


        // Write your code here.

        System.out.println("String: " + s);
        System.out.println("Double: " + d);
         System.out.println("Int: " + i);
    }
}
