Java.Streams.Name the main classes of input/output streams.

✅ Main Classes of Input/Output Streams

🔹 1. Byte Streams

Use these for binary data (files, images, audio, etc.)

📥 Input Streams (read bytes):

• InputStream (abstract base class)
• FileInputStream – reads bytes from a file
• BufferedInputStream – adds buffering
• ByteArrayInputStream – reads from a byte array
• DataInputStream – reads primitive types (int, double, etc.)
• ObjectInputStream – reads serialized Java objects
• PipedInputStream – used for inter-thread communication

📤 Output Streams (write bytes):

• OutputStream (abstract base class)
• FileOutputStream – writes bytes to a file
• BufferedOutputStream – adds buffering
• ByteArrayOutputStream – writes to a byte array
• DataOutputStream – writes primitives
• ObjectOutputStream – writes serialized objects
• PipedOutputStream – connects to PipedInputStream

🔹 2. Character Streams

Use these for text (Unicode characters)

📥 Readers (read characters):

• Reader (abstract base class)
• FileReader – reads from a file
• BufferedReader – efficient line-by-line reading
• CharArrayReader – reads from a char array
• StringReader – reads from a string
• InputStreamReader – bridges byte → character stream

📤 Writers (write characters):

• Writer (abstract base class)
• FileWriter – writes to a file
• BufferedWriter – buffered writing
• CharArrayWriter – writes to char array
• StringWriter – writes to string
• OutputStreamWriter – bridges character → byte stream
