Displaying a text File

[Jdinesh Tiwari]

Hi, All

According to this code specified in book
I am unable to see my File
as per the command specified at command promt
please see the last line n the comment very first.

Though my file exists D:

/* Display a text file.
	To use this program, specify the name
	of the file that you wan to see.
	For example, to see a file called TEST.TXT
	use the following command line.

	java ShowFile TEST.TXT
*/
import java.io.*;
class ShowFile{
		public static void main(String[]args)
		throws IOException
		{
		int i;
		FileInputStream fin;
		
		try{
		fin = new FileInputStream(args[0]);
		}catch(FileNotFoundException e){
		System.out.println("File Not Found");
		return;
		}catch(ArrayIndexOutOfBoundsException e){
		System.out.println("USage: ShowFile File");
		return;
		}
		
		
		//read character until EOF is encountered
		do {
		i = fin.read();
		if(i!=-1) System.out.println((char)i);
		} while(i!=-1);
		
		fin.close();
		}
	}

seems to work for me.

Can you be more specific in what the problem is? Did you compile it? Did you run it? What were the exact commands you gave? Did it show an error? what is in the file you are trying to display?

Hi, fred
No, there is no problem neither in its compilation nor in execution

Actually i had a file in D: with name TEST.TXT and want to see that very file

and for file display i was trying this program, but i am unable to see my file (i want that it should get open)

Seems good to me also.. It is displaying in my machine also.
Is your java file and the .txt file in the same directory? if no the store them into the same directory any run the program.
