Building the Right Environment to Support AI, Machine Learning and Deep Learning
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();
}
}
}
