One common conversion task is transforming byte arrays into strings. Different encodings (e. Jul 23, 2025 · A byte is 8 bits of binary data so do byte array is an array of bytes used to store the collection of binary data. For example, when reading data from a file, network socket, or dealing with binary data that needs to be presented as text. We write the contents of the byte array to the OutputStream using the write method, specifying the offset (0 in this case) and the number of bytes to write (bytesRead). This process is essential in various scenarios, such as reading data from network sockets, file I/O operations, or handling binary data that needs to be represented as text.
