Question

Ok, so I had problems with this before in C++.  Now I'm dealing with it in Java, and need a touch of help.  Here's what I have to do:

Write a program that

? Asks the user for the names of two files

? Opens the first file for reading

? Opens the second file for writing

? Reads the contents of the first file, changes all characters to uppercase, and stores the results in the second file

The second file will be a copy of the first file, except that all the characters will have changed case.  

The two files can be found HERE:

http://www.filedropper.com/skippie

Here's what I have so far.....

import java.util.Scanner;              // allows for Scanner class

import java.io.*;                     // allows for File I/O

public class ErnestTeeUpperFile {

    public static void main(String[] args) {

        Scanner keyboard = new Scanner (System.in);   //create scanner object for keyboard input

       System.out.print("Enter the name of the file to be READ: ");    //gets file name and stores it

       String readFile = keyboard.nextLine();

        System.out.print("Enter the name of the file to be WRITTEN: ");   //gets file name and stores it

        String writeFile = keyboard.nextLine();

        PrintWriter outputFile = new PrintWriter(readFile);

....here's where my brain slams on the brakes.  Any help is appreciated!

Explanation / Answer

//I have put lots off efforts for your problem .

import java.io.*;

import java.util.*;

class FileRead

{

public static void main(String args[])

{

try{

FileInputStream fstream = new FileInputStream("firstfile.txt");

DataInputStream in = new DataInputStream(fstream);

BufferedReader br = new BufferedReader(new InputStreamReader(in));

String strLine;

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

{

String new_words="";

Set<String> words = new HashSet<String>(Arrays.asList(strLine.split(" ")));

new_words=words.toUpperStirng();

try {

FileWriter fileWriter =new FileWriter(secondfile.txt);

BufferedWriter bufferedWriter =new BufferedWriter(fileWriter);

bufferedWriter.write(new_words);

bufferedWriter.close();

}

catch(IOException ex)

{

System.out.println("Error writing to file '"+ fileName + "'");

}

in.close();

}catch (Exception e){

System.err.println("Error: " + e.getMessage());

}

}
