Date: 2025-04-18

This article demonstrates three efficient Kotlin methods for reading large files, minimizing memory consumption. It showcases BufferedReader for line-by-line text file reading, useLines with sequences for lazy text processing, and InputStream for binary files, processing data in chunks. Each method uses a use block for resource management. Choosing the right method—BufferedReader for line-by-line text, useLines for lazy text processing, or InputStream for binary files—is crucial for optimal performance with large files.
