ObjectStreamException

AI-generated Key Takeaways

• ObjectStreamException is the superclass for all exceptions related to Java Object Streams, extending IOException.

• It indicates issues during object serialization or deserialization, such as data corruption, invalid classes, or incompatible objects.

• Several specific subclasses like InvalidClassException and StreamCorruptedException provide more detailed error information.

• It has two protected constructors: one taking a detailed message and another with no arguments.

• Inherited methods from Throwable allow for stack trace analysis and exception chaining.

public abstract class ObjectStreamException extends IOException

Known Direct Subclasses InvalidClassException, InvalidObjectException, NotActiveException, NotSerializableException, OptionalDataException, StreamCorruptedException, WriteAbortedException InvalidClassException Thrown when the Serialization runtime detects one of the following problems with a Class.  InvalidObjectException Indicates that one or more deserialized objects failed validation tests.  NotActiveException Thrown when serialization or deserialization is not active.  NotSerializableException Thrown when an instance is required to have a Serializable interface.  OptionalDataException Exception indicating the failure of an object read operation due to unread primitive data, or the end of data belonging to a serialized object in the stream.  StreamCorruptedException Thrown when control information that was read from an object stream violates internal consistency checks.  WriteAbortedException Signals that one of the ObjectStreamExceptions was thrown during a write operation.

Superclass of all exceptions specific to Object Stream classes.

Inherited Method Summary

From class java.lang.Throwable

synchronized final void	addSuppressed(Throwable exception) Appends the specified exception to the exceptions that were suppressed in order to deliver this exception.
synchronized Throwable	fillInStackTrace() Fills in the execution stack trace.
synchronized Throwable	getCause() Returns the cause of this throwable or null if the cause is nonexistent or unknown.
String	getLocalizedMessage() Creates a localized description of this throwable.
String	getMessage() Returns the detail message string of this throwable.
StackTraceElement[]	getStackTrace() Provides programmatic access to the stack trace information printed by printStackTrace().
synchronized final Throwable[]	getSuppressed() Returns an array containing all of the exceptions that were suppressed, typically by the try-with-resources statement, in order to deliver this exception.
synchronized Throwable	initCause(Throwable cause) Initializes the cause of this throwable to the specified value.
void	printStackTrace() Prints this throwable and its backtrace to the standard error stream.
void	printStackTrace(PrintWriter s) Prints this throwable and its backtrace to the specified print writer.
void	printStackTrace(PrintStream s) Prints this throwable and its backtrace to the specified print stream.
void	setStackTrace(StackTraceElement[] stackTrace) Sets the stack trace elements that will be returned by getStackTrace() and printed by printStackTrace() and related methods.
String	toString() Returns a short description of this throwable.

From class java.lang.Object

Object	clone() Creates and returns a copy of this Object.
boolean	equals(Object obj) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of Class that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait(long timeout, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
final void	wait(long timeout) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
final void	wait() Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.
