Re: Revised Question on File Processing

Dear Group,

I was trying to read a file get the output in the form of words and

trying to compare with the words generated from a sentence. I was

trying to write the following code.

It is giving me an output of the file in the form of words, but after

that I am not being able to attach any more processings. It is

throwing an exception as,

Exception in thread "main" java.lang.NullPointerException

    at FileIntake1.main(FileIntake1.java:21)

But if I write the code with try and catch, true exception is not

there, but no output.

And I am just new to Java my question is if you write try and catch a

file, how one post processes a file within try? Isn't there a smart

solution?

And how would I go here?

I am bit new to Java if you can kindly direct.

Regards,

Subhabrata.

#1) Code No: 1

import java.io.*;

public class FileIntake1 {

    /**

     * @param args

     */

    public static void main(String[] args) throws IOException {

        FileReader fr = new FileReader("C:\\FileIO\\JAVADICT1.txt");

         BufferedReader br = new BufferedReader(fr);

         String s2="Moscow is the Capital of Russia";

         String [] s3=s2.split(" ");

         int l2=s3.length;

        String str;

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

         //System.out.println("The Strings In the File are:");

            System.out.println(str);

            String [] s1=str.split(" ");

            int l1=s1.length;

            for(int x = 0; x < l1; x = x+1) {

                 //System.out.print("value of x : " + x );

                 System.out.println(s1[x]);

            }

        br.close();

    }

}
