How to Read a .file Extension in Java Like a .txt File

In Java, reading files irrespective of their extension, such as .file, is straightforward and can be done using typical I/O methods. While the file extension might suggest different content or usage, the process of reading text from a file remains constant across different file extensions.

Using BufferedReader and FileReader

One of the most common and efficient ways to read a file in Java is by using BufferedReader in conjunction with FileReader. Here's how you can achieve this:

Explanation:

FileReader: Reads the content of the file.

BufferedReader: Buffers the characters for efficient reading.

readLine(): Reads the file line by line, till end of the file.

try-with-resources: Ensures closing of resources automatically.

Using Files and Paths

Java 7 introduced the Files and Paths classes which offer a simplistic approach to file reading. Here’s an alternative method using these classes for reading a file:

Explanation:

Exception Handling: Catches and handles any possible IOException.

Conclusion

Reading a .file extension file in Java is not different from reading a .txt file. Java’s I/O package provides robust and flexible methods to achieve file reading, ensuring that developers can handle different file types uniformly. By using either BufferedReader with FileReader or the modern Files and Paths approach, you can efficiently read and process the contents of your files.
