Algorithms are needed to design computer programs. An algorithm will have input data and should produce output data after it has carried out a process. This is known as the input-process-output model.

A program inputs its data from the standard input device by calling Java’s System.in.read() method. Look in the SDK documentation and you’ll discover a class called System.
