My Code:

    Scanner kb = new Scanner (System.in);
    String ans;
      ans = kb.nextLine ();

    System.out.println(ans.split(" "));

Please, read the documentation: https://docs.oracle.com/javase/7/docs/api/java/lang/String.html#split(java.lang.String)

After this, it's easy to see why the following code works and why yours does not:

import java.util.Scanner;

public class Main
{
    public static void main(String[] args)
    {
        String line = new Scanner(System.in).nextLine();
        String[] results = line.split(" ");
        for (String result : results)
            System.out.println(result);
    }
}

If it's still not clear: String.split() returns an array of strings (the results of the split) and you have to iterate through them and print them one by one.
