Question

please can you help me solve this question, i have written the codebut for some reason it says
"java.io.file not found expection"

the questiion is

Write a program that asks the user for the names of two files. Thefirst file should be opened for reading and the second file shouldbe opened for writing. The program should read the contents of thefirst file, change all characters to uppercase, and store theresults in the second files. The second file will be a copy of thefirst file, except that all the characters will be uppercase. UseNotepad or another text editor to create a simple file that can beused to test the program.


what i wrote is

import java.util.Scanner;     // Needed for theScanner class
importjava.io.*;            // Needed for file classes

public class Uppercase2
{
    public static void main(String[] args) throwsIOException
    {
       String filename;
        String filename2;
        String writing;

        // Create a Scannerobject for keyboard input.
        Scanner keyboard = newScanner(System.in);

        // Get the firstfilename.
        System.out.print("Enterthe first filename: ");
        filename =keyboard.nextLine();

        // get the secondfilname
        System.out.print("Enterthe second filename: ");
        filename2 =keyboard.nextLine();

        // Open the readingfile.
        FileReader freader = newFileReader(filename);
        BufferedReader inputFile= new BufferedReader(freader);

        // open output file
        FileWriter fwriter = newFileWriter(filename2);
        PrintWriter outputFile =new PrintWriter(fwriter);

        //writing =inputFile.readLine();

        while ((writing =inputFile.readLine()) != null)
        {
           System.out.println(writing);


        // writing =inputFile.readLine();
           String upper = writing.toUpperCase();
           System.out.println(upper);
           outputFile.println(upper);
        }

        // close IO streams
        outputFile.close();
        inputFile.close();
    }
}
