Method

voidcopyFile(FileChannel in, FileChannel out)
Optimized copy from one file to another 
long position = 0;
long read;
while ((read = in.transferTo(position, 16 * 1024, out)) > 0) {
    position += read;
voidcopyFile(FileInputStream fromFile, FileOutputStream toFile)
Creates the specified toFile as a byte for byte copy of the fromFile. 
FileChannel fromChannel = null;
FileChannel toChannel = null;
try {
    fromChannel = fromFile.getChannel();
    toChannel = toFile.getChannel();
    fromChannel.transferTo(0, fromChannel.size(), toChannel);
} finally {
    try {
...
voidcopyFile(final File in, final File out)
Copy the input file to output file 
FileChannel inChannel = new FileInputStream(in).getChannel();
FileChannel outChannel = new FileOutputStream(out).getChannel();
try {
    inChannel.transferTo(0, inChannel.size(), outChannel);
} catch (IOException e) {
    throw e;
} finally {
    if (inChannel != null) {
...
voidcopyFile(final File in, final File out)
copy File 
RandomAccessFile f1 = new RandomAccessFile(in, "r");
RandomAccessFile f2 = new RandomAccessFile(out, "w");
try {
    FileChannel c1 = f1.getChannel();
    FileChannel c2 = f2.getChannel();
    try {
        c1.transferTo(0, f1.length(), c2);

...
voidcopyFile(final File input, final File output)
This method can be used to copy a file from one place to another. 
FileInputStream in = null;
FileOutputStream out = null;
try {
    in = new FileInputStream(input);

FileInputStream srcInput = null;
FileChannel srcChannel = null;
...
voidcopyFile(final File src, final File dst)
Copies the source file to the destination file 
if (!src.exists()) {
    throw new FileNotFoundException("File does not exist: " + src.getAbsolutePath());
if (!dst.exists()) {
    dst.createNewFile();
FileChannel source = null;
FileChannel destination = null;
...
booleancopyFile(final File srcFile, final File destFile)
Copy a file. 
return copyFile(srcFile, destFile, false);
voidcopyFile(final File srcFile, final File destFile)
