December 1, 2023 - Looking at the common usage practices, we can see, for example, that PrintWriter is used to write formatted text, FileOutputStream to write binary data, DataOutputStream to write primitive data types, RandomAccessFile to write to a specific position, and FileChannel to write faster in larger files. Some of the APIs of these classes do allow more, but this is a good place to start. This article illustrated the many options of writing data to a file using Java...
