int that specifies the first element of the array used to store the first incoming byte The third parameter is an int that specifies the total number of bytes to read from the connection This version of the read() method also returns either the total number of bytes read or a 1 You can skip bytes in an input stream by calling the skip() method The skip() method requires one parameter, which is a long that specifies the number of bytes to skip The skip() method returns either the total number of bytes skipped or a 1 indicating the end of the stream The InputStream class uses a blocking technique whenever data is unavailable from the open connection The blocking technique requires the InputStream class to wait until data becomes available before the application continues Blocking also occurs with the OutputStream class where the application pauses until data is sent You can avoid blocking by calling the available() method before calling the read() method The available() method returns the number of bytes available to be read from the open connection If bytes are available, call the read() method; otherwise avoid calling the read() method because it will create a block until bytes are available to be read by your program Although your application reads bytes sequentially from a stream, you can read bytes downstream (ahead) and then return upstream to read additional bytes by using the technique called marking Before reading downstream, call the mark() method to mark your current position in the stream The mark() method requires an int parameter that specifies how many bytes you can read ahead You return to the marked position in the stream by calling the reset() method A word of caution: marking may not be available in all implementations; therefore you should call the markSupported() method, which returns a boolean value indicating whether or not marking is supported The close() method terminates the input stream, not the connection Rarely will you need to call the close() method because the input stream is automatically closed when the instance of the InputStream is out of scope However, it is always a good practice to call the close() method to free up resources.

An interesting and useful feature offered by javautil is the ability to schedule a task for execution at some future time The classes that support this are Timer and TimerTask Using these classes, you can create a thread that runs in the background, waiting for a specific time When the time arrives, the task linked to that thread is executed Various options allow you to schedule a task for repeated execution, and to schedule a task to run on a specific date Although it was always possible to manually create a task that would be executed at a specific time using the Thread class, Timer and TimerTask greatly simplify this process Timer and TimerTask work together Timer is the class that you will use to schedule a task for execution The task being scheduled must be an instance of TimerTask Thus, to schedule a task, you will first create a TimerTask object and then schedule it for execution using an instance of Timer TimerTask implements the Runnable interface; thus, it can be used to create a thread of execution Its constructor is shown here: TimerTask( ) TimerTask defines the methods shown in Table 18-8 Notice that run( ) is abstract, which means that it must be overridden The run( ) method, defined by the Runnable interface, contains the code that will be executed Thus, the easiest way to create a timer task is to extend TimerTask and override run( ) Once a task has been created, it is scheduled for execution by an object of type Timer The constructors for Timer are shown here: Timer( ) Timer(boolean DThread) Timer(String tName) Timer(String tName, boolean DThread) The first version creates a Timer object that runs as a normal thread The second uses a daemon thread if DThread is true A daemon thread will execute only as long as the rest of the program continues to execute The third and fourth constructors allow you to specify a name for the Timer thread The methods defined by Timer are shown in Table 18-9.
