Explanation / Answer

Hi, Please find my implementation.

Please let me know in case of any issue.

import java.io.File;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.IOException;

public class CopyOfJoke {

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

       File inFile = new File("joke.txt");

       File outFile = new File("copyJoke.txt");

       FileInputStream fis = new FileInputStream(inFile);

       FileOutputStream fos = new FileOutputStream(outFile);

       int i;

       char c;

       // read till the end of the file

       while((i = fis.read())!=-1) {

           // converts integer to character

           c = (char)i;

           fos.write(c);

       }

       fis.close();

       fos.close();

       if (outFile.exists()) {

           System.out.println("copyJoke.txt exist");

       }else{

           System.out.println("copyJoke.txt does not exist");

       }

   }

}
