ByteArrayInputStream class

 

††††††††††††††††† See  InputStream class  for descriptions of ByteArrayInputStreamís inherited methods.They are:

 

available( ) ††††††††††††††††† Tells how many bytes can be gotten without blocking.

close( ) ††††††††††††††††††††††† Close the stream.

mark( int readAheadLimit )Mark the present position in the stream.

markSupported( ) ††††††† Tell whether this stream supports the mark(...) operation.

read( )††††††††††††††††††††††† Read a single byte, returning it as the low end of an int.

read( byte[ ] b )†††††††††† Read bytes into a byte array.

read( byte[ ] b, int off, int len)Read bytes into a portion of a byte array.

ready( ) ††††††††††††††††††††††† Tell whether this stream is ready to be read.

reset( )††††††††††††††††††††††† Reset the stream to the beginning.

skip( long n )††††††††††††† Skip characters.

 

 

See CharArrayReader class.†††† ByteArrayInputStream reads from a byte array the same way thatCharArrayReaderreads from a char array.Its methods and constructors work the same.

 

Neither its constructors or its read( ) methods throw any IOExceptions.

 

This example using .read( )returns either the next byte from the array, in an int, or -1 in that int to indicate EOF.i.e.

 

import java.io.*;

 

byte[ ] b = { 0,1,2,3,4,5,6,7,8,9} ;

ByteArrayInputStream bais = new ByteArrayInputStream( b );††† // constructor indicates array to be read from

int x;

†† while ( (x = bais.read( ) ) != -1 ) {

†††††† System.out.print( x );

††† }
