Write a java program to accept filename and display it's content (byte by byte) using FileInputStream class.

 import java.io.*;  //importing module for file and FileInputStream Class
import java.util.*;
class MyFile
{
 File f;   //declaring file object
 MyFile()
 {
 Scanner s= new Scanner(System.in);
 System.out.println("Enter the path of file: ");  //accepting file path
 String path=s.next();
 System.out.println("Enter the name of file: ");  //accepting file name
 String name=s.next();
 f=new File(path,name);  //initializing file object
 }
 void display()   //creating a method to display content of file
 {
 try
 {
 if (f.exists() && f.isFile())  // checking whether entered file name exists and whether it is file or not...
 {
 FileInputStream fin = new FileInputStream(f);    //creating the FileInputStream object in order to read the content of file
 System.out.println("Content of File: ");
 while(true)
 {
 int i=fin.read();
 if (i==-1)      // When file pointer reaches to the end of the file read function returns -1 
 break;
 System.out.print((char)i);  //TypeCasting-read function returns the content of file in int format (i.e. ASCII) so we need to convert it into char
 }
 }
 }catch(Exception e)   //FileInputStream class object throws exceptions so we need to catch those exceptions using try and catch block
 {
 System.out.println(e);
 }
 }
}
class TestMyFile
{
 public static void main(String args[])
 {
 MyFile obj= new MyFile();  //cretating the object of our class which is defined above and it will automatically call the constructor
 obj.display();  // calling the display method 
 }
}
