Fig. 16.Input/output (I/O) subsystem. Devices and Interfaces The I/O subsystem inFig. 16contains both devices and interfaces. Aperipheral device(orI/O device) performs some function for the computer. AnI/O interface(ordevice interface) controls the operation of a peripheral device according to...
This class combines a Service (representing the input method component to the system with the InputMethod interface that input methods must implement. This base class takes care of reporting your InputMethod from the service when clients bind to it, but provides no standard implem...

Output Available bytes in the file: 39 Data read from the file: This is a line of text inside the file In the above example, we have created an input stream using the FileInputStream class. The input stream is linked with the file input.txt. InputStream input = new FileInputStream(...
interface, writeExternal and readExternal, are called to save and restore the objects state. When implemented by a class they can write and read their own state using all of the methods of ObjectOutput and ObjectInput. It is the responsibility of the objects to handle any versioning that ...
