Ace Java 2025: Rock Your 'Thinking in Java' Challenge!

Question: 1 / 510

In which scenario would you use ByteArrayInputStream?

When reading from a database

When working with files

When reading from a memory area

When working with files (B), you would typically use FileInputStream instead, as it is optimized for reading bytes from a file. Similarily, when reading from a database (A), you would use a JDBC query to retrieve data, not ByteArrayInputStream. When downloading data from the internet (D), you would likely use an InputStream from URL or a similar mechanism designed for remote retrieval, not ByteArrayInputStream. Therefore, the only scenario where you would truly use ByteArrayInputStream is when you need to read from a memory area (C) such as a byte array. This can be useful when dealing with packets of data in network programming or when working with large arrays of binary data in memory.
