Class Overview

A Closeable is a source or destination of data that can be closed. The close method is invoked to release resources that the object is holding (such as open files).

Summary

Public Methods
abstract void	close() Closes this stream and releases any system resources associated with it.

Public Methods

public abstract void close ()

Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect.

Throws

IOException	if an I/O error occurs
