runtime error - java scanner does not accept two words with space in between -

i'm trying create simple project ask user true or false , if true scanner gonna keep storing category name in arraylist. , works fine until enter 2 words space in category name "first second" example reason jump condition true or false , check have entered word true or false , execute catch clause . i've tried using both scanner.next or nextline , nextline jump true or false without asking category name. please help. thank much.

public class mainclass {   public static boolean check = false; public static void main(string[] args) {     scanner in = new scanner(system.in);      categories c = new categories();      system.out.println("please enter true if want add category \n or false if not");      try {         check = in.nextboolean();     } catch (inputmismatchexception e) {         system.out.println("sorry must put true or false!!!");         system.exit(0);              }       while (check) {         system.out.println("please enter category name");         c.category.add(in.next().tostring());         system.out.println("do want add more true or false");          try {             check = in.nextboolean();         } catch (inputmismatchexception e) {             system.out.println("sorry must put true or false!!!");             system.exit(0);         }      }      system.out.println("thank categories added");     system.out.println(c.category);      } 

}

you can use inputstreamreader wrapped around bufferedreader:

bufferedreader reader = new bufferedreader(new inputstreamreader(system.in)); reader.readline(); // read 2 words
