In the previous post , we have seen few examples and methods of ArrayList. In this post , we will see how to find size of ArrayList in Java.

Find size of ArrayList:

We use the method size() in java to find out the total size of array list i.e. total items in array list. It returns integer value. Let’s understand this with an example.

Syntax:

public int size();

Example:

import java.util.ArrayList;

public class ArrayListEx {

	public static void main(String[] args) {
		ArrayList<String> cityList = new ArrayList<String>();
		cityList.add("Bangalore");
		cityList.add("Delhi");
		cityList.add("Pune");
		cityList.add("Noida");
		
		System.out.println("Total Size of ArrayList :" +cityList.size());
		cityList.remove("Pune");
		
		System.out.println("Total Size of ArrayList after removing pune :" +cityList.size());
	}
}

Output:
