// importing all the packages required
import java.io.*;
import java.util.*;

class StoreData {
  // creating Array List which store another Array List into it
  static ArrayList<ArrayList<Object>> myArrayList = new ArrayList<>();

  // storing In the Array List
  public static void storeDataInArray(String course, int mark) {
    
    // creating an Array list to store data
    ArrayList<Object> temp = new ArrayList<>();
  
    // storing data in temp Array List
    temp.add(course);
    temp.add(mark);
    
    // storing the temp Array List into myArrayList
    myArrayList.add(temp);

    // printing the elements of Array List (myArrayList)
    System.out.println(myArrayList + " Added success in the Array List");
  }

  // Main function
  public static void main(String[] args) {
   Scanner sc = new Scanner(System.in);

   // taking Course input from user
   System.out.println("Enter the Course");
   String course = sc.nextLine();
   // taking mark input from user
   System.out.println("Enter the Individual mark");
   int mark = sc.nextInt();
  
   // calling the function to store data
   storeDataInArray(course, mark);
 }
}
