WebByteArrayOutputStream (int size) Creates a new byte array output stream, with a buffer capacity of the specified size, in bytes. Method Summary Methods inherited from class java.io. OutputStream flush, write Methods inherited from class java.lang. Object clone, equals, finalize, getClass, hashCode, notify, notifyAll, wait, wait, wait Field Detail WebThe byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored. Subclasses of OutputStream must provide an implementation for this method. Parameters: b - the byte. Throws: IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed. write
