Why can't I enter a string in Scanner(System.in), when calling nextLine()-method?

Question

How does this program actually work...?

import java.util.Scanner;

class string
{
    public static void main(String a[]){
        int a;
        String s;
          


        

Answer 1

 s=scan.nextLine();

It returns input was skipped.

so you might use

 s=scan.next();
