Import java.io. *; / ** * @Author user * @version 1.0 * / public class fileinputstreamDemo {
public static void main (String args []) {if (args.length = 1!) {System.err.println ( "Syntax - FileInputStreamDemo file"); return;} try {InputStream fileInput = new FileInputStream (args [0] Int Data = fileinput.read (); while (data! = -1) {system.out.write (data); data = fileinput.read ();} fileinput.close ();} catch (ooException ie) {System.err.Println ("I / O Error -" IOE);}}}
Question: When I enter a file, I can't display the content or not display all the contents of the file. Which one can tell me?
I am a rookie ~~
