How to Access Elements in a List in Java ?

Answer

To access elements in a list in Java, you can use indexing or iterate over the list using loops.

✐ Examples

1 Access Elements Using Index

In this example,

We create an ArrayList named numList with integer elements.
We access elements by their index using the get() method and print them to standard output.

Java Program

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<Integer> numList = new ArrayList<>();
        numList.add(1);
        numList.add(2);
        numList.add(3);
        int element = numList.get(2); // Accessing element at index 2
        System.out.println("Element at index 2: " + element);
    }
}

Output

Element at index 2: 3

2 Access Elements Using Loop

In this example,

We create an ArrayList named strList with string elements.
We iterate over the list using a for-each loop and print each element to standard output.

Java Program

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<String> strList = new ArrayList<>();
        strList.add("Apple");
        strList.add("Banana");
        strList.add("Cherry");
        for (String str : strList) {
            System.out.println(str);
        }
    }
}

Output

Apple
Banana
Cherry
