#1

import java.util.*;

class Main{
public static void main(String[] args){
Scanner sc = new Scanner(System.in);
int t = sc.nextInt();
while(t>0){
int k = sc.nextInt();

        String[] arr = new String[k];
            
        for(int i=0; i<arr.length ; i++){
            
            arr[i] = sc.nextLine();
           
       }
          
         for(String val : arr){
            System.out.print(val + " ");
        }
        
        System.out.println();
        t--;
}   
    
    
}

}

You should first, take the number of test cases and the size of the array both using scanner. nextLine() because when you are accepting the first string your control is not where the string is inputted by the user.

No… I didn’t get answer… Can you please write it in a code format… and tell me where I did mistake…

you could use, it like this.,
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
int k = Integer.parseInt(in.readLine());
String A[] = new String[k];
for(int i=0;i<k;i++)A[i] = in.readLine();
