I\'m getting \'List Full\' when I try to add 2nd student.

//Driver.java

import java.util.Scanner;

public class Driver {

   public static void main(String[] args) {
       new Driver();

   }

       System.out.println(\"Select option below\");
       System.out.println(\"\");
      
       while(true) {
           System.out.println(\"1: Add Student\");
           System.out.println(\"2: Display Student\");
           System.out.println(\"3: Exit\");
          
           int userChoice = input.nextInt();

           }
       }
   }
   //Student[] newStudent = new Student[3];

   }
}
