java - Reading integers from a line -

-

i'm trying read 2 integers on same line. 

scanner a=new scanner(system.in); x=a.nextint(); y=a.nextint();

now, if input

3 4
3 4

x = 3 , y = 3. tried using a.usedelimiter("\\s") doesn't work.

there must error elsewhere in code. works fine me.

import java.util.scanner;  class main {     public static void main(string[] args)     {         scanner = new scanner(system.in);         int x = a.nextint();         int y = a.nextint();         system.out.println("x = " + x + ", y = " + y);     } }

input:

3 4 3 4

output:

x = 3, y = 4
