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();









	}
}


#2) Code No: 2
import java.io.*;

public class FileInput{

   public static void main(String args[]){

   try{
      byte bWrite [] = {11,21,3,40,5};
      OutputStream os = new FileOutputStream("C:\\FileIO\
\JAVADICT1.txt");
      for(int x=0; x < bWrite.length ; x++){
         os.write( bWrite[x] ); // writes the bytes
      }
      os.close();

      InputStream is = new FileInputStream("C:\\FileIO\
\JAVADICT1.txt");
      int size = is.available();

      for(int i=0; i< size; i++){
         System.out.print((char)is.read() + "  ");
      }
      is.close();
   }catch(IOException e){
      System.out.print("Exception");
   }
   }
