import java.util.*;
public class test {
    public static void main(String[] args)
    {

        //Set n =25
        int n = 25;

        //ArrayList of Integer type with size,n=25 
        ArrayList<Integer> list = new ArrayList<Integer>(n); 
        for(int i = 0;i<n;i++){

           //Assign -1 to all the objects of the array list,list
            list.add(-1);
        }
        
        //Add 1001 to the list
        list.add(1001);
        //Add 1100 to the list
        list.add(1100);
        //Add 1110 to the list
        list.add(1110);
        //Reset the number of elements in the list becomes 28
        //Use size() method to get the size of the list.
        n=list.size();


        //for loop to print the list
        for(int i = 0;i<n;i++){
            System.out.print(list.get(i) + " ");
        }
