Using scanner to read input statement

Question

i'm writing code to read simple statement of words like "one two three", and put each word into an array String [] token, i wanted to input the statement using Scanner but it only read the first word. when i use the main method to input the statement it works well. can i know what is my mistake?

here are the 2 Codes:

//Using main method:

public class MyLangyage {
    public static void main(String[] args) {
        String statement = "one two three";
        screen(statement);
    }
    public static void screen(String statement) {
        String token[]= statement.split(" ");

        for (int i = 0; i < token.length; i++) {
            System.out.println(token[i]);
        }
    }
}

the result at the console will be:

one two three

//Using The Scanner:

import java.util.Scanner;

public class MyLangyage {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        String statement = scanner.next();
        screen(statement);
    }
    public static void screen(String statement) {
        String token[]= statement.split(" ");

        for (int i = 0; i < token.length; i++) {
            System.out.println(token[i]);
        }
    }
}

if i write at console:

one two three

then press enter the result will be:

one

You are using scanner.next() which gets the next word it reads. If you want to read the whole line and then split use scanner.nextLine()

Either split a whole input line, or use the Scanner to get one token at a time. Don't do both.

If you want to pull in multiple words from a Scanner, then you'll have to use scanner.next() more than once -- indeed, once per word.
