See InputStream class for descriptions of ByteArrayInputStream’s 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 that CharArrayReader reads 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 );
}
