This chapter discusses input and output for Java 5.0 and above. Most programs input data, process it, and then output the results. This chapter discusses ways to input data from the keyboard and output results to the monitor. Later chapters will discuss input and output from disk files and other media.
Note: Some books show input done using classes written by the book's author. To use them, you must install a package from a CD or from a web site. This is OK. You can use these notes (with standard Java methods) along with your text without any interference.
When a computer program does an input operation, in which direction does the data flow?
