What is Java IO EOFException?
java.io.EOFException. Signals that an end of file or end of stream has been reached unexpectedly during input. This exception is mainly used by data input streams to signal end of stream.

What is Java Lang ClassNotFoundException?

What is ObjectInputStream in Java?
The Java ObjectInputStream class ( java. io. ObjectInputStream ) enables you to read Java objects from an InputStream instead of just raw bytes. Otherwise reading objects will fail. Normally you will use the ObjectInputStream to read objects written (serialized) by a Java ObjectOutputStream .
What happens if input stream is not closed?
OutputStream , say FileOutputStream , after writing to a file, if we don’t close() the output stream, the data that we intended to write in the file remains in the buffer and is not written to the file. So it becomes necessary to close() an OutputStream .
How do I check if InputStream is empty?
No, you can’t. InputStream is designed to work with remote resources, so you can’t know if it’s there until you actually read from it. You may be able to use a java….
- available() tells you if there’s data ready to be read, it doesn’t necessarily tell you if the stream is empty.

Persistent storage of objects can be accomplished by using a file for the stream. The method writeObject is used to write an object to the stream.
