In this Tutorial we want to describe you a code that show you the use of exception class in java .Exceptions handling is the key in Java, that handle run time errors and  indicate  a calling method whenever an abnormal condition occurred. This tutorial helps you in understanding  exception handling appropriately in  programs and designs. The steps involved in the program are described below:-

BufferedReader br = new BufferedReader(new FileReader("girish")):-Buffered reader is a class that reads text from a character-input stream. Here we are creating Buffered reader which generally read request made of a Reader.

String s = br.readLine():- This method read each line of the text and buffer request is stored in the string s.

System.out.println("File not found."):-This is the Exception message which is to be displayed if the particular file is not found.

SimpleExceptionHandling.java 

import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;

public class SimpleExceptionHandling {
    public static void main(String args[]){
        try{
         BufferedReader br = new BufferedReader(new FileReader("girish"));
         String s = br.readLine();  
         System.out.println(s);
        }
       catch(FileNotFoundException fne)
        {
        System.out.println("File not found.");
        }
