How do I implement an ArrayList in Java?

How do I implement an ArrayList in Java?

To implement an ArrayList in Java, you can use the ArrayList class from the java.util package. Here's a simple example:

import java.util.ArrayList;

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

What are the advantages of using ArrayList over arrays?

ArrayLists are dynamic in size, allowing you to add or remove elements easily, while arrays have a fixed size. Additionally, ArrayLists provide built-in methods for searching, sorting, and manipulating data.

Can you show me how to remove an element from an ArrayList?

Sure! You can remove an element from an ArrayList using the remove() method. Here's an example:

list.remove("Banana");
System.out.println(list);

How do I iterate through an ArrayList?

You can iterate through an ArrayList using a for loop or an enhanced for loop. Here's an example using the enhanced for loop:

for (String fruit : list) {
    System.out.println(fruit);
}
