When we need to write an array of bytes to a file in Java, there are a few options. We can use either the built-in APIs or a few common libraries.

In this quick tutorial, we’re going to learn several different ways to write a Java byte array to a file. We’ll start at the beginning, using the Java IO package. Next, we’ll look at an example using Java NIO. After that, we’ll use Google Guava and Apache Commons IO.
