Method

booleancopy(File inFile, File outFile)
This method copies one file to another location 
if (!inFile.exists()) {
    return false;
FileChannel in = null;
FileChannel out = null;
try {
    in = new FileInputStream(inFile).getChannel();
    out = new FileOutputStream(outFile).getChannel();
...
voidcopy(File pSourceFile, File pTargetFile)
copy 
if (!pSourceFile.getCanonicalPath().equals(
        pTargetFile.getCanonicalPath())) {
    pTargetFile.getParentFile().mkdirs();
    FileInputStream lFIS = new FileInputStream(pSourceFile);
    FileOutputStream lFOS = new FileOutputStream(
            pTargetFile.getCanonicalPath());
    copy(lFIS, lFOS);
    lFOS.close();
...
voidcopy(File source, File target, boolean append)
Copies source to target. 
Check.arg().validFile(source);
Check.arg().notNull(target);
if (source.getCanonicalPath().equals(target.getCanonicalPath()))
    throw new IllegalArgumentException(
            "source and target resolve to the same path = "
                    + source.getCanonicalPath());
InputStream in = null;
OutputStream out = null;
...
voidcopy(File sourceFile, File destinationFile)
copy 
FileReader reader = null;
FileWriter writer = null;
try {
    reader = new FileReader(sourceFile);
    writer = new FileWriter(destinationFile);
    int data = reader.read();
    while (data != -1) {
        writer.write(data);
...
voidcopy(File sourceFile, File targetFile)
Copy the source file to the target file. 
copy(sourceFile, targetFile, false);
booleancopy(File sourceFile, File targetFile, boolean overwrite)
Copy the source file to the target file while optionally permitting an overwrite to occur in case the target file already exists. 
boolean overwriteOccurred = false;
if (targetFile.exists()) {
    if (!overwrite) {
        throw new FileAlreadyExistsException("Target file "
                + targetFile + " already exists");
    } else {
        overwriteOccurred = true;
FileInputStream fis = new FileInputStream(sourceFile);
FileOutputStream fos = new FileOutputStream(targetFile);
fis.getChannel().transferTo(0, sourceFile.length(),
        fos.getChannel());
fis.close();
fos.flush();
fos.close();
return overwriteOccurred;
voidcopy(File sourceFile, String destinction)
copy 
if (!sourceFile.exists())
    return;
File dest_f = new File(destinction);
if (!dest_f.exists())
    dest_f.mkdirs();
if (sourceFile.isDirectory()) {
    java.io.File[] files = sourceFile.listFiles();
    for (int i = 0; files != null && i < files.length; i++) {
...
voidcopy(File src, File dest)
copy 
if (src.isDirectory()) {
    if (!dest.exists()) {
        dest.mkdir();
    String files[] = src.list();
    for (String file : files) {
        File srcFile = new File(src, file);
        File destFile = new File(dest, file);
...
booleancopy(String input, String output)
This class copies an input file to output file 
int BUFSIZE = 65536;
FileInputStream fis = new FileInputStream(input);
FileOutputStream fos = new FileOutputStream(output);
try {
    int s;
    byte[] buf = new byte[BUFSIZE];
    while ((s = fis.read(buf)) > -1) {
        fos.write(buf, 0, s);
...
voidcopy(String pSourceFile, String pTargetFile)
copy 
copy(new File(pSourceFile), new File(pTargetFile));
