(Real beginner) Removing space before the first word when switched

This one little problem has been bugging me for 1 whole hour.

Code Java:

---

import java.util.Scanner;
public class Project8 {
 
	public static void main(String[] args) 
	{
		Scanner keyboard = new Scanner (System.in);
 
		String s1, s2;
 
		System.out.println("Enter a line of text. No punctuation please.");
		s1 = keyboard.next();
		s2 = keyboard.nextLine();
 
		System.out.println("I have rephrased that line to read:");
		System.out.println("" + s2 + " " + s1);
	}
 
}

---

If I run this, I get:

-Enter a line of text. No punctuation please.
-What the hell
-I have rephrased that line to read:
- the hell What

I want the space in the rephrased line before "the" gone...How IS IT POSSIBLE TO REMOVE?

Hello and welcome to the Java Programming Forums.

This can be easily fixed by updating:

System.out.println("" + s2 + " " + s1);

to

System.out.println(s2.trim() + " " + s1);

the .trim() method removes the white space.
