Reads a File and displays the it on the Screen

Write a Java program that reads a file and displays the file on the screen, with a line number before each line.

Program Code in JAVA:

import java.io.*;

class FileRead

{

public static void main(String[] args) throws Exception

{

File f=new File("FileRead.java");

FileReader fr=new FileReader(f);

BufferedReader br=new BufferedReader(fr);

String str=br.readLine();

int i=1;

while((str=br.readLine())!=null)

{

System.out.println(i++ +" "+str);

}

fr.close();

}

}

Program Output:

c:\java>javac FileRead.java

c:\java>java FileRead

1 class FileRead

2 {

3 public static void main(String[] args) throws Exception

4 {

5 File f=new File("FileRead.java");

6 FileReader fr=new FileReader(f);

7 BufferedReader br=new BufferedReader(fr);

8 String str=br.readLine();

9 int i=1;

10 while((str=br.readLine())!=null)

11 {

12 System.out.println(i++ +" "+str);
