OutputStream is an abstract class in java.io that represents an output stream of bytes — i.e., it lets you write raw binary data to some destination.

The class you’re looking for is DataInputStream.

SequenceInputStream in Java is a class used to combine two or more input streams into one so they can be read sequentially, one after the other, as if they were a single continuous stream.

✅ What Is PushbackInputStream? PushbackInputStream is a special kind of InputStream that allows you to “unread” or push back bytes into the stream — so they can be read again later. It’s like a stream with an “undo” buffer — … Continue reading →

Great question, Stanley! 🧠 Let’s explore the subclasses of InputStream and understand what each is used for. InputStream is the abstract base class for reading raw bytes in Java.

✅ 1. java.io — Traditional I/O (Streams API) This is the main package that contains most of the classic input/output stream classes.

✅ 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 … Continue reading →

🧠 Let’s walk through the types of input and output streams in Java — these are part of the traditional java.io package. Java organizes streams into two main categories:
