How to get the first element of an ArrayList in Java
java1min read
In this tutorial, we are going to learn about how to get the first element of an ArrayList in Java.
Consider, we have a following ArrayList:
List list = Arrays.asList[10, 20, 30, 40];
To get the first element of a ArrayList, we can use the list.get[] method by passing 0 as an argument.
0 is refers to first element index.
Here is an example, that returns the first element 10 from the following ArrayList:
import java.util.Arrays;
import java.util.List;
public class Main
{
public static void main[String[] args] {
List list = Arrays.asList[10, 20, 30, 40];
System.out.println[list.get[0]];
}
}
Output:
10
