Uses of IOException in java.io

Subclasses of IOException in java.io

class	CharConversionException This is the top level class for character conversion exceptions.
class	EOFException This End Of File (EOF) exception is thrown when a program encounters the end of a file or stream during an operation.
class	FileNotFoundException This IO exception is thrown when a file specified by a program cannot be found.
class	InterruptedIOException This IO exception is thrown when a program reading or writing to a stream is interrupted.
class	InvalidClassException A problem was found with the class of one of the objects being serialized or deserialized.
class	InvalidObjectException The object graph loaded (deserialized) can be validated by a collection of validator objects.
class	NotActiveException Some methods in ObjectInputStream and ObjectOutputStream can only be called from a nested call to readObject() or writeObject().
class	NotSerializableException When an implementation of ObjectOutput.writeObject() is passed an object that is not serializable, it will throw this type of exception.
class	ObjectStreamException This is the superclass of all exceptions that can happen when serializing or deserialing objects.
class	OptionalDataException When readObject() encounters primitive types (int, char, etc) instead of an object instance in the input stream, this type of exception will be thrown.
class	StreamCorruptedException When readObject() cannot read an object from the input stream due to missing information (cyclic reference that doesn't match previous instance or missing class descriptor for instance to be loaded) this type of exception is thrown.
class	SyncFailedException This IO exception is thrown when the method sync() in FileDescriptor failed to complete.
class	UnsupportedEncodingException This IO exception is thrown when a program asks for a particular character converter and it is not available.
class	UTFDataFormatException This IO exception is thrown when a program attempts to read a UTF-8 String and the encoding is incorrect.
class	WriteAbortedException This type of exception is thrown by readObject() when it detects an exception marker in the input stream.

Methods in java.io that throw IOException

abstract int	InputStream.read() Reads the next byte of data from the input stream.
int	InputStream.read(byte[] b) Reads some number of bytes from the input stream and stores them into the buffer array b.
int	InputStream.read(byte[] b, int off, int len) Reads up to len bytes of data from the input stream into an array of bytes.
long	InputStream.skip(long n) Skips over and discards n bytes of data from this input stream.
int	InputStream.available() Returns the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream.
void	InputStream.close() Closes this input stream and releases any system resources associated with the stream.
void	InputStream.reset() Repositions this stream to the position at the time the mark method was last called on this input stream.

InvalidPropertiesFormatException

Methods in java.util that throw IOException

void	Properties.load(InputStream inStream) Reads a property list (key and element pairs) from the input stream.
void	Properties.store(java.io.OutputStream out, java.lang.String header) Writes this property list (key and element pairs) in this Properties table to the output stream in a format suitable for loading into a Properties table using the load method.
