Working with ArrayList Operations

ArrayList has an overloaded method that accepts a string, as well as an Integer, as an argument. The remove method can remove elements based on the string, along with the index.

import java.util.ArrayList;public class ArrayListOperations { public static void main(String[] args) { ArrayList colorNames = new ArrayList();colorNames.add("Saffron");colorNames.add("White");colorNames.add("Green");//Removing using the contentscolorNames.remove("White");//Removing using the indexcolorNames.remove(0);System.out.println(colorNames);} }

Expected output:

[root@mypc]# java ArrayListOperations[Green]
