How to take multiple string as input

#1

I am not able to take multiple string from user.I have written this code but get exception.
import java.util.*;
public class Main {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
int n=sc.nextInt();
String[] arr=new String[n];
int i;
Scanner sc2 = new Scanner(System.in);
for(i=0;i<n;i++)
arr[i]=sc2.nextLine();
for(i=0;i<n;i++)
System.out.println(arr[i]);

}

}

public static void main(){
Scanner scn=new Scanner(System.in);
int n=scn.nextInt();
String s=scn.next();/////used scn.next() to take input as string
}
