Java For Loop Issue

Use the following code. Comments in the code explain changes.

import java.util.Scanner;
import java.util.Random;
public class Run {

public static void main(String[] args) {
    // TODO Auto-generated method stub
    Scanner input = new Scanner(System.in);
    Random rand = new Random();

    System.out.println("How many people will play???");
    int playernum = input.nextInt();
    input.nextLine(); //ADDED LINE

    String players[] = new String[playernum];

    for(int i = 0; i < playernum; i++){
        System.out.println("Who is player #" + (i+1)+"?");
        players[i] = input.nextLine();
    }

    System.out.println("The winner is: " + players[rand.nextInt(playernum)]);

}

}

We added input.nextLine(); because input.nextInt(); leaves a leftover new line character that we need to clear out. It was putting this new line character as player 1

Use input.next() instead of input.nextLine() in the for loop. That way, the unused new line character won't be a problem, like @BheshGurung explains in his answer.

I think your issue is on this line players[i] = input.nextLine();.

I think what you're looking for is, players[i] = input.next();

"Advances this scanner past the current line and returns the input that was skipped. This method returns the rest of the current line, excluding any line separator at the end." See the API description here.
