Java program demonstrating the usage of FileInputStream in java.io package-Different Way

Java Logo

The FileInputStream class creates an InputStream that you can use to read bytes from a file.

//Java Program demonstrating the FileInputStream Class in java.io package

FileInputStreamDemo1.java

Check out the while loop used for looping the File

import java.io.*;

class FileInputStreamDemo1{

                public static void main(String[] args){

                                try{

                                                File f = new File(“Hello.txt”);

                                                int size;

                                                FileInputStream fis = new FileInputStream(f);

                                                System.out.println(“Total Available Bytes: ” + (size = fis.available()));

                                                int i = 0;

                                                while(i!=-1){

                                                                i = fis.read();

                                                                if(i!=-1)

                                                                System.out.print((char)i);

                                                }                             

                                }

                                catch(Exception e){

                                                e.printStackTrace();

                                }

                }

}
