To Display a Text File Using Java IO

Here is a Java Program to Display a text file.

To use this program, specify the name  of the file that you want 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 characters until EOF is encountered
    do {
      i = fin.read();
      if(i != -1) System.out.print((char) i);
    } while(i != -1);

    fin.close();
  }
}
