lastIndexOf Method in Java

The lastIndexOf(Object) method of the class java.util.ArrayList returns the index of the last occurrence of the specified element in this list, or -1 if this list does not contain the element.

Example

import java.util.ArrayList;

public class ArrayListDemo {
   public static void main(String[] args) {
      ArrayList<String> arrlist = new ArrayList<String>(5);
      arrlist.add("G");
      arrlist.add("E");
      arrlist.add("F");
      arrlist.add("M");
      arrlist.add("E");
      System.out.println("Size of list: " + arrlist.size());
      for (String value : arrlist) {
         System.out.println("Value = " + value);
      }
      int retval=arrlist.lastIndexOf("E");
      System.out.println("The last occurrence of E is at index " + retval);
   }
}

Output

Size of list: 5
Value = G
Value = E
Value = F
Value = M
Value = E
The last occurrence of E is at index 4
