Method

voidcopyFile(File sourceFile, File destFile)
copy File 
FileInputStream inStream = new FileInputStream(sourceFile);
try {
    FileOutputStream outStream = new FileOutputStream(destFile);
    try {
        inStream.getChannel().transferTo(0, sourceFile.length(), outStream.getChannel());
    } finally {
        outStream.close();
} finally {
    inStream.close();
voidcopyFile(File sourceFile, File destFile)
copy File 
if (!destFile.exists()) {
    destFile.createNewFile();
FileInputStream from = null;
FileOutputStream to = null;
try {
    from = new FileInputStream(sourceFile);
    to = new FileOutputStream(destFile);
...
voidcopyFile(File sourceFile, File destFile)
Copies the source file to the destination file Also creates any interim directories needed 
if (!sourceFile.isFile())
    throw new Exception("ERROR NOT A FILE: " + sourceFile.getPath());
File destParent = new File(destFile.getParent());
if (!destParent.exists()) {
    destParent.mkdirs();
FileInputStream from = null;
FileOutputStream to = null;
...
voidcopyFile(File sourceFile, File destFile, boolean overwrite, boolean preserveLastModified)
Method to copy a file from a source to a destination specifying if source files may overwrite newer destination files and the last modified time of destFile file should be made equal to the last modified time of sourceFile. 
if (overwrite || !destFile.exists() || destFile.lastModified() < sourceFile.lastModified()) {
    if (destFile.exists() && destFile.isFile())
        destFile.delete();
    File parent = new File(destFile.getParent());
    if (!parent.exists())
        parent.mkdirs();
    FileInputStream in = new FileInputStream(sourceFile);
    FileOutputStream out = new FileOutputStream(destFile);
...
voidcopyFile(File sourceFile, File destinationFile)
Copies the specified source file's content to the destination file's location. 
InputStream in = null;
OutputStream out = null;
try {
    if (!destinationFile.getParentFile().exists()) {
        destinationFile.getParentFile().mkdirs();
    in = new FileInputStream(sourceFile);
    out = new FileOutputStream(destinationFile);
...
voidcopyFile(File sourceFile, File destinationFile)
A method that creates a copy of file at new file path 
destinationFile.getParentFile().mkdirs();
InputStream is = new FileInputStream(sourceFile);
try {
    redirectInputStream2File(is, destinationFile);
} catch (IOException e) {
    if (destinationFile.exists()) {
        destinationFile.delete();
    is.reset();
    redirectInputStream2File(is, destinationFile);
booleancopyFile(File sourceFile, File targetDir)
copy File

if (sourceFile.isDirectory()) { 
    targetFile.mkdir();
    File[] dir = sourceFile.listFiles();
    for (int i = 0; i < dir.length; i++) {

    while ((c = fis.read(buffer)) != -1) {
        fos.write(buffer, 0, c);
    fis.close();
    fos.close();
    return true;
voidcopyFile(File sourceFile, File targetDir)
Copy a file on the file system from a source to a destination

    return false;
InputStream inputStream = null;
OutputStream outputStream = null;
try {
    inputStream = new FileInputStream(sourceFile);
    outputStream = new FileOutputStream(targetFile);
...
voidcopyFile(File sourceFile, File targetFile)
copy File 
if (sourceFile.isDirectory()) {
    copyDir(sourceFile, targetFile);
} else {
    File parent = targetFile.getParentFile();
    if (!parent.exists()) {
        if (!parent.mkdirs()) {
            throw new IOException("Failed to create directory " + parent.getAbsolutePath());
    final InputStream is = new FileInputStream(sourceFile);
    final OutputStream os = new FileOutputStream(targetFile);
