Why Use ArrayList of String Objects in Reading Lines from a Text File?

Consider writing a program that reads the lines of any text file into a sequential list of lines. Which of the following is a good reason to implement the list with an ArrayList of String objects rather than an array of String objects?

An ArrayList of String objects, as opposed to an array of String objects, provides greater flexibility and scalability when reading lines from a text file into a program. This is due to ArrayLists' ability to dynamically resize.

Benefits of Using ArrayList of String Objects:

Flexibility: One of the main advantages of using an ArrayList of String objects when reading lines from a text file is the flexibility it offers. Unlike arrays, ArrayLists can resize themselves dynamically, making it easier to add new lines from the file without worrying about the size limitations.

Dynamic Resizing: ArrayLists are dynamic data structures that can automatically adjust their capacity as needed. This means that as you read lines from the text file, the ArrayList will expand or shrink accordingly, optimizing memory usage and improving efficiency.

Scalability: When working with text files of varying sizes, using an ArrayList of String objects is more scalable compared to an array. You don't need to predefine the size of the list, allowing you to handle different file lengths seamlessly. The dynamic nature of ArrayLists makes them ideal for scenarios where the size of the input data is unknown.

Efficiency: By using an ArrayList, you can enhance the efficiency of your program when reading lines from a text file. The ability to resize dynamically reduces unnecessary memory allocation and ensures optimal performance during file processing.

Ease of Implementation: Implementing an ArrayList of String objects is straightforward and convenient. With built-in methods for adding, removing, and accessing elements, ArrayLists simplify the process of managing a collection of lines from a text file.

To sum up, choosing to implement a list with an ArrayList of String objects offers numerous advantages, including flexibility, dynamic resizing, scalability, efficiency, and ease of implementation. These benefits make ArrayLists a preferable option for reading lines from text files and other scenarios where the size of the data may vary unpredictably.
