Copy file or directory from one location to another location

I am using this program without any problem. You can use this to copy a file from one location to another location. And i am trying to handle all kind of situation that if the file exist or not or is it a directory or many more. This code have "static" copyFile mothod so u can call it from any where or any other classs file. This code is working fine, use this code and enjoy.

package com.javaxpert.io;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;

public class FileCopy {
    // copyFile function begins from here.
    public static void copyFile(File varFromFile, File varToFile)
            throws IOException {
        // First make sure the source file exists, is a file, and is readable.
        if (!varFromFile.exists())
            System.err.println("no such source file: " + varFromFile);
        if (!varFromFile.isFile())
            System.err.println("can't copy directory: " + varFromFile);
        if (!varFromFile.canRead())
            System.err.println("source file is unreadable: " + varFromFile);
        // If the destination is a directory, use the source file name
        // as the destination file name
        if (varToFile.isDirectory())
            varToFile = new File(varToFile, varFromFile.getName());
        // If the destination exists, make sure it is a writable file
        // and ask before overwriting it. If the destination doesn't
        // exist, make sure the directory exists and is writable.
        if (varToFile.exists()) {
            if (!varToFile.canWrite())

            System.out.print("Overwrite existing file " + varToFile.getName()
                    + " ? (Y/N): ");

            // writable. If getParent() returns null, then the directory is
