How to get rid of unwanted line in output - Java

The goal of this program is to print its even-indexed and odd-indexed characters as space-separated strings on a single line. But for some reason when I go to output, there's always an extra line shown here.

import java.util.*;

public class program1{
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in); // Init Scanner
        int x = sc.nextInt();
        for (int i = 0; x >= i; i++){ //Loops 
            String word = sc.nextLine();
            String temp1 = "", temp2 = "";
            for (int j = 0; word.length() > j; j++){
                if (j % 2 == 0){
                    temp1 += word.charAt(j);
                } else if (j % 2 != 0){
                    temp2 += word.charAt(j);
                }
            }
            System.out.println(temp1 + " " + temp2);
        } sc.close();
    }
}

Using sc.nextLine() method I changed for (int i = 0; x >= i; i++){ // Loops to for (int i = 0; x > i; i++){ // Loops Which fixed the java.util.NoSuchElementException: No line found error

Using int x = Integer.parseInt(sc.nextLine()); method I also have to change I changed for (int i = 0; x >= i; i++){ // Loops to for (int i = 0; x > i; i++){ // Loops as it is making me input three strings instead of the desired two.

Thank you to all the people who helped me!

The simplest solution to get rid of the "extra line" is doing

int x = Integer.parseInt(sc.nextLine());

instead of

int x = sc.nextInt();
