Example

The following example shows the usage of java.util.Arraylist.lastIndexOf() method.

package com.c4learn.arraylist;
import java.util.ArrayList;
public class ArrayListExamples {
  public static void main(String args[]) {
    // Create ArrayList 1
    ArrayList<String> arrlist1 = new ArrayList<String>(5);
    // Fill Elements in ArrayList 1
    arrlist1.add("A");
    arrlist1.add("B");
    arrlist1.add("C");
    arrlist1.add("D");
    arrlist1.add("B");
    arrlist1.add("B");
    // Print Array List
    int pos = arrlist1.lastIndexOf("B");;
    // Print Element's Position
    System.out.println("Index of Last Occurance of B : " + pos);
  }
}

package com.c4learn.arraylist;

import java.util.ArrayList;

public class ArrayListExamples {

public static void main(String args[]) {

// Create ArrayList 1

ArrayList<String> arrlist1 = new ArrayList<String>(5);

// Fill Elements in ArrayList 1

arrlist1.add("A");

arrlist1.add("B");

arrlist1.add("C");

arrlist1.add("D");

arrlist1.add("B");

// Print Array List

int pos = arrlist1.lastIndexOf("B");;

// Print Element's Position

System.out.println("Index of Last Occurance of B : " + pos);

}

Output :

Index of Last Occurance of B : 5

1	Index of Last Occurance of B : 5
