This is my code:

Scanner kb = new Scanner(System.in);        
    int a = kb.nextInt();
    String word = kb.nextLine();
    System.out.println("Hello");        
    System.out.println("World");
    System.out.println(word);

The result is:

123
Hello
World

123 is my input for integer, but it didn't ask for any input for my word variable. Different case for .next(). It works but It can only print 1 word instead of 2+ if I put more than 2 words in my String word variable.

Did you try to use `while` loop? `while (kb.hasNext()) { }`. – dmitryro Jul 04 '18 at 16:19
Use 123 231. Here, "123" goes to "a" and "231" goes to word – Shaunak Patel Jul 04 '18 at 16:27
@dmitryro Not yet. How does the hasNext() work ? – Reinaldo Jul 04 '18 at 16:33
@ShaunakPatel My apologies for the misstyped in my question. It works when I put my nextLine() above my nextLine() but It wont work if I put my nextInt() above my nextLine(). (Saying that the first input must be an integer) – Reinaldo Jul 04 '18 at 16:42
