Explanation / Answer

Please Ignore my above code :

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileReader;

import java.io.FileWriter;

import java.io.IOException;

public class TextReader {

private static String readFileAsString(String filePath) throws IOException

{

StringBuffer fileData = new StringBuffer();

BufferedReader reader = new BufferedReader(

new FileReader(filePath));

char[] buf = new char[1024];

int numRead=0;

while((numRead=reader.read(buf)) != -1){

String readData = String.valueOf(buf, 0, numRead);

fileData.append(readData);

}

reader.close();

return fileData.toString();

}

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

{

String readData=readFileAsString("E:/1.txt");

readData=readData.replaceAll("[\s]+", " ");

readData=readData.replaceAll("[.][\s]", ". ");

readData=readData.replaceAll("[?][\s]", "? ");

readData=readData.replaceAll("[!][\s]", "! ");

String[] lines=readData.split(" ");

try {

File file = new File("E:/2.txt");

// if file doesnt exists, then create it

if (!file.exists())

{

file.createNewFile();

}

FileWriter fw = new FileWriter(file.getAbsoluteFile());

BufferedWriter bw = new BufferedWriter(fw);

for(String e:lines)

{

e=e.replace(e.substring(0, 1), e.substring(0, 1).toUpperCase());

bw.write(e);

bw.newLine();

}

bw.close();

} catch (IOException e) {

e.printStackTrace();

}

}

}
