Making a File Read-only Using Java

Files have multiple properties and they are interesting to use. In fact, your own file system can be developed using them. Create a file named PATH.txt and try this program twice to see how the setReadOnly() method works. Explore and enjoy!

import java.io.File;public class ReadOnlyFile {   public static void main(String[] args)    {      //File to choose     String fileNameWithPath = "C:/PATH.txt";     File file = new File(fileNameWithPath);           System.out.println("File is writeable: " + file.canWrite());     //If the file is writable, then making it read-only     if (file.canWrite())     {        System.out.println("File is writable. Making it read-only now");        file.setReadOnly();     }   }}
