What is object InputStream?

An ObjectInputStream deserializes primitive data and objects previously written using an ObjectOutputStream. … ObjectInputStream ensures that the types of all objects in the graph created from the stream match the classes present in the Java Virtual Machine. Classes are loaded as required using the standard mechanisms.

How do you read InputStream?

InputStream reads bytes with the following read methods :

  1. read(byte[] b) — reads up to b. length bytes of data from this input stream into an array of bytes.
  2. read(byte[] b, int off, int len) — reads up to len bytes of data from this input stream into an array of bytes.
  3. read() — reads one byte from the file input stream.

What is StringWriter in Java?

The Java. io. StringWriter class is a character stream that collects its output in a string buffer, which can then be used to construct a string. Closing a StringWriter has no effect. The methods in this class can be called after the stream has been closed without generating an IOException.

How do you use SequenceInputStream?
