How do you move a file from one location to another? When I run my program any file created in that location automatically moves to the specified location. How do I know which file is moved?

You can move a file or directory by using the move(Path, Path, CopyOption...) method. The move fails if the target file exists, unless the REPLACE_EXISTING option is specified.
Right-click the file or folder you want, and from the menu that displays click Move or Copy. The Move or Copy window opens. Scroll down if necessary to find the destination folder you want. If you need to, click on any folder you see to access its subfolders.
Another common way to copy a file with Java is by using the commons-io library. The latest version can be downloaded from Maven Central. Then, to copy a file we just need to use the copyFile() method defined in the FileUtils class. The method takes a source and a target file.
The proper steps to upload a file to FTP serverConnect and login to the server. Enter local passive mode for data connection. Set file type to be transferred to binary. Create an InputStream for the local file.
Now what we will do to move the file in Java is, provide the path in method parameter with the same name, which will result in moving the file from our original directory to our destination directory with the same name. Here is how our final Java code will look like.
The first method utilizes Files package for moving while the other method first copies the file to destination and then deletes the original copy from the source. Using Files.Path move () method: Renaming and moving the file permanently to a new location.
An instance of java.nio.file.Path is obtained using the FileSystem.getPath () method. The Path instance is an encapsulation around a file or a directory in the file system. (Note – In Unix a directory is also a file;the same logic extends in Java running on Windows and a Path instance can hold a file or a directory instance on Windows as well)
We can use Files.move () API to move file from one directory to another. Following is the syntax of the move method.
myFile.renameTo(new File("/the/new/place/newName.file"));
File#renameTo does that (it can not only rename, but also move between directories, at least on the same file system).
Renames the file denoted by this abstract pathname.
Many aspects of the behavior of this method are inherently platform-dependent: The rename operation might not be able to move a file from one filesystem to another, it might not be atomic, and it might not succeed if a file with the destination abstract pathname already exists. The return value should always be checked to make sure that the rename operation was successful.
If you need a more comprehensive solution (such as wanting to move the file between disks), look at Apache Commons FileUtils#moveFile

With Java 7 or newer you can use Files.move(from, to, CopyOption... options).
E.g.
Files.move(Paths.get("/foo.txt"), Paths.get("bar.txt"), StandardCopyOption.REPLACE_EXISTING);
See the Files documentation for more details

Java 6
public boolean moveFile(String sourcePath, String targetPath) {
File fileToMove = new File(sourcePath);
return fileToMove.renameTo(new File(targetPath));
}
Java 7 (Using NIO)
public boolean moveFile(String sourcePath, String targetPath) {
boolean fileMoved = true;
try {
Files.move(Paths.get(sourcePath), Paths.get(targetPath), StandardCopyOption.REPLACE_EXISTING);
} catch (Exception e) {
fileMoved = false;
e.printStackTrace();
}
return fileMoved;
}
File.renameTo from Java IO can be used to move a file in Java. Also see this SO question.
