Are you referring to Java?

// java version "1.8.0_191"

// Java(TM) SE Runtime Environment (build 1.8.0_191-b12)

// Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)// openjdk 11.0.2 2019-01-15

import java.util.ArrayList;

public class LastElementArrayList {

static public void main(String argv[]) {

ArrayList<String> arrayList = new ArrayList<String>();

arrayList.add("a");

arrayList.add("b");

arrayList.add("c");

arrayList.add("d");

String last = arrayList.get(arrayList.size()-1);

System.out.println("Last Item: " + last);

}

}

// Output:
