.add()

The .add() method is used for adding elements to instances of the ArrayList class.

Syntax

An element can be added to an instance of ArrayList by being passed to the .add() method:

arrayListInstance.add(element);

Example

import java.util.ArrayList;
public class Students {
public static void main(String[] args) {
// Create an ArrayList called studentList, which initially holds []
ArrayList<String> studentList = new ArrayList<String>();
// Add students to the ArrayList
studentList.add("John");
studentList.add("Lily");
studentList.add("Samantha");
studentList.add("Tony");
System.out.println(studentList);
}
}

The output from the snippet above would look like this:

[John, Lily, Samantha, Tony]
