[java] How to copy file from one location to another location?

I want to copy a file from one location to another location in Java. What is the best way to do this?

Here is what I have so far:

import java.io.File;
import java.io.FilenameFilter;
import java.util.ArrayList;
import java.util.List;
public class TestArrayList {
    public static void main(String[] args) {
        File f = new File(
        List<String>temp=new ArrayList<String>();
        temp.add(0, "N33");
        temp.add(1, "N1417");
        temp.add(2, "N331");
        File[] matchingFiles = null;
        for(final String temp1: temp){
            matchingFiles = f.listFiles(new FilenameFilter() {
                public boolean accept(File dir, String name) {
                    return name.startsWith(temp1);


This does not copy the file, what is the best way to do this?

This question is related to java io

The answer is

You can use this (or any variant):

Files.copy(src, dst, StandardCopyOption.REPLACE_EXISTING);

Also, I'd recommend using File.separator or / instead of \\ to make it compliant across multiple OS, question/answer on this available here.

Since you're not sure how to temporarily store files, take a look at ArrayList:

List<File> files = new ArrayList();

To move a List of files into a single directory:

List<File> files = ...;
String path = "C:/destination/";
for(File file : files) {
        (new File(path + file.getName())).toPath(),
