There is a space in the string, but when I run program, it returns -1, that means there aren't spaces in the string Here's the code:
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String s = scan.next();
System.out.println(s.indexOf(' '));
}
}
Scanner.next() returns the next token in the input, and by default, tokens are whitespace separated. i.e. s is guaranteed not to contain spaces.
Maybe you meant String s = scan.nextLine();?
