Sunday, 10 May 2015

There we will remove one element of arraylist using remove().

import java.util.ArrayList;

public class RemoveElement {

    public static void main(String[] args) {

       ArrayList<String> arr = new ArrayList<String>();

       // add element in arraylist
       arr.add("c");
       arr.add("php");
       arr.add("html");
       arr.add("java");

       // print arraylist
       System.out.println("Before Remove Element ArrayList is = " + arr);

       /*
       * Removes the element at the specified position in this
           list. Shifts any subsequent elements to the left
       */

       arr.remove(1);

       System.out.println("After Remove Element ArrayList is="+arr);
