Can I have some help?! If you run this, you find this error;
java.lang.NullPointerException

public class Solution {
private static List<String> strings;
public static void main(String[] args) throws Exception {
//write your code here
BufferedReader inp = new BufferedReader (new InputStreamReader(System.in));
for (int i = 0; i < 5; i++)
{
String T= inp.readLine(); // for taking a number as an input
strings.add(i, T.toString());
}
System.out.println(strings.get(0));
}
}
