0231 The Byte Stream Classes
<![CDATA[
Byte streams are defined by using two class hierarchies. At the top are two abstract classes: InputStream and OutputStream.
Stream Class Meaning
BufferedInputStream Buffered input stream
BufferedOutputStream Buffered output stream
ByteArrayInputStream Input stream that reads from a byte array
ByteArrayOutputStream Output stream that writes to a byte array
DataInputStream An input stream that contains methods for reading the Java standard data types
DataOutputStream An output stream that contains methods for writing the Java standard data types
FileInputStream Input stream that reads from a file
FileOutputStream Output stream that writes to a file
FilterInputStream Implements InputStream
FilterOutputStream Implements OutputStream
InputStream Abstract class that describes stream input
ObjectInputStream Input stream for objects
ObjectOutputStream Output stream for objects
OutputStream Abstract class that describes stream output
PipedInputStream Input pipe
PipedOutputStream Output pipe
PrintStream Output stream that contains print( ) and println( )
PushbackInputStream Input stream that supports one-byte "unget," which returns a byte to the input stream
RandomAccessFile Supports random access file I/O
SequenceInputStream Input stream that is a combination of two or more input streams that will be read sequentially, one after the other
Methods from InputStream
int available()
Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream.
void close()
Closes this input stream and releases any system resources associated with the stream.
void mark(int readlimit)
Marks the current position.
boolean markSupported()
if this input stream supports the mark and reset methods.
abstract int read()
Reads the next byte.
int read(byte[] b)
Reads some number of bytes and stores them into the buffer array b.
int read(byte[] b, int off, int len)
Reads up to len bytes of data into an array of bytes.
void reset()
Repositions this stream to the position at the time the mark method was last called.
long skip(long n)
Skips over and discards n bytes.
