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<String> colorNames = new ArrayList<String>();
colorNames.add("Saffron");
colorNames.add("White");
colorNames.add("Green");
//Removing using the contents
colorNames.remove("White");

//Removing using the index
colorNames.remove(0);

System.out.println(colorNames);
} 
}

Expected output:

[root@mypc]# java ArrayListOperations
[Green]
