What does the method add(E element) do in java?

The add(E e) method of the java.util.ArrayList class appends the specified element E to the end of the list.

Example:

import java.util.ArrayList;

public class ArrayListDemo {
   public static void main(String[] args) {
      ArrayList<Integer> arrlist = new ArrayList<Integer>(5);
      arrlist.add(15);
      arrlist.add(20);
      arrlist.add(25);
      for (Integer number : arrlist) {
         System.out.println("Number = " + number);
      }
   }
}

Output:

Number = 15
Number = 20
Number = 25
