What Does the Method getInt Do in Java

The get(int index) method of the java.util.ArrayList class returns the element at the specified position in this 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(22);
      arrlist.add(30);
      arrlist.add(40);
      for (Integer number : arrlist) {
         System.out.println("Number = " + number);
      }
      int retval=arrlist.get(3);
      System.out.println("Retrieved element is = " + retval);
   }
}

Output

Number = 15
Number = 22
Number = 30
Number = 40
Retrieved element is = 40
