How To Practise Hidden File Inwards Java- Representative Tutorial

In final article nosotros saw how to banking concern stand upwards for hidden files inward Java together with right away nosotros volition run across how to enshroud file inward Java or make hidden file inward Java. As nosotros said File API inward Java doesn’t render whatever method to brand a file hidden inward Java but nonetheless you lot tin apply merely about quick tricks to enshroud files from Java program. Like inward Unix surround whatever file whose names start out amongst point (.) is hidden together with hence you lot tin advert your  file starting amongst point (.)  and your File volition live on hidden inward Linux or Unix Environment. On Windows you lot require to lead execute DOS ascendence equally stated inward how to execute rhythm out commands from Java past times using Runtime.getRuntime.exec(“command”) to brand the file hidden inward Windows. Here is an instance of making file hidden inward Windows using Java Program.

Runtime.getRuntime().exec("attrib +H HiddenFileExample.java");

How to brand a File hidden from Java Program

Now amongst JDK7 which introduced Automatic Resource Management , fork bring together framework  and String inward Switch Case , you lot convey a whole novel laid upwards of File API inward java.nio.file package  which provides lots of useful  File together with Attributed related functionality similar Path which encapsulate Path for whatever file.

Hide a File inward Java5 amongst Example

Here is  consummate code instance you lot tin work to make a File hidden from Java without using JDK7, disadvantage of this approach is that you lot are invoking rhythm out ascendence lead from Java code which makes it platform subject together with goes against coffee top dog payoff of write in i lawsuit together with read anywhere:

void setHiddenProperty(File file) throws InterruptedException, IOException {
    Process p = Runtime.getRuntime().exec("attrib +H " + file.getPath());
    p.waitFor();
}

here telephone cry upwards to p.waitFor() is optional but  calling waitFor() ensures that file volition seem hidden equally presently equally business office exit.

Now nosotros volition run across code instance to enshroud a file inward Java7 using novel java.nio.file packet together with novel classes similar “Path” which encapsulate file path inward diverse operating organization together with can live on used to  operate on files, directories, together with other types of files inward Java.

Code Example of making a file hidden inward JDK7

Here is consummate code instance of hiding a File inward windows from Java7 novel features.

Path path = FileSystems.getDefault().getPath("directory", "hidden.txt");
Boolean hidden = path.getAttribute("dos:hidden", LinkOption.NOFOLLOW_LINKS);
if (hidden != zero && !hidden) {
    path.setAttribute("dos:hidden", Boolean.TRUE, LinkOption.NOFOLLOW_LINKS);
}

That’s all on how to enshroud file inward both Java5 together with Java7 past times using either Runtime.exec() or novel java.nio.file packet introduced inward JDK7. allow me know if you lot know whatever other agency of making a file hidden from Java program together with nosotros tin include that instance here.
