Though small, USB Write Protect is a useful utility which helps protect data written to connected USB devices which prevents data on USB drives from being modified or deleted.Using the program helps prevent accidental deletion of modification of files on your thumb drive (or other connected devices). It works by activating OS-based features, much like the Windows Explorer properties window.Activating USB Write Protect is easy and protection is activated seconds after plugging in a device to a USB 2 or USB 3.0 mass storage device. Devices should be unplugged before running USB Write Protect as it is only activated when a device is recognized.USB Write Protect provides a very basic function which is useful in certain situations and not to be written off, especially since its a niche freeware application designed for one function.Features of USB Write Protect
- Auditing: Keep track of all write operations on the USB drive.
- Comprehensive Logging: View a detailed log of all write operations on the drive.
- Data Protection: Prevent all write operations on the drive and protect your data against accidental deletion.
- Drive Scanning: Scan the USB drive for potential threats.
- Easy to Use: Intuitive user interface makes it easy to use.
- File Backup: Automatically backup files to the USB drive.
- File Encryption: Encrypt files on the USB drive for additional security.
- File Filtering: Selectively allow or block certain file types from being written to the USB drive.
- File Recovery: Recover accidentally deleted files quickly and easily.
- File Removal: Safely remove files without leaving any traces.
- File Shredding: Permanently delete files to protect against data recovery.
- File Whitelisting: Allow only certain files to be written to the USB drive.
- Flexible Configuration: Customize the protection settings to suit your needs.
- Multi-Drive Support: Manage multiple USB drives from a single interface.
- Password Protection: Secure your USB drive against unauthorized access with password protection.
Protected class member (method or variable) is just like package-private (default visibility), except that it also can be accessed from subclasses.
Since there's no such concept as 'subpackage' or 'package-inheritance' in Java, declaring class protected or package-private would be the same thing.
As you know default is for package level access and protected is for package level plus non-package classes but which extends this class (Point to be noted here is you can extend the class only if it is visible!). Let's put it in this way:
Since there is no way to restrict this class being subclassed by only few classes (we cannot restrict class being inherited by only few classes out of all the available classes in a package/outside of a package), there is no use of protected access specifiers for top level classes. Hence it is not allowed.
So If we are allowed to make a class protected then we can access it inside the package very easily but for accessing that class outside of the package we first need to extend that entity in which this class is defined which is its package.
And since a package can not be extended (can be imported), defining a class protected will again make it package-private which is similar to defining it as default which we can already do.Therefore there is no benefit of defining a class private it will only make things ambiguous.
Now what if "protected class foo" allow ? protected main characteristic is subclass, so the outer(package) SHOULD(due to up-to scope, but still it's optional) provide style of subclass, i.e. sub-package, or package A extends package B, but we know no such thing. So protected can't use full potential(main scope is subclass-wide) in top-level which the outer is package(i.e. no such sub-package thing), but protected can use full potential in nested class which the outer is class(i.e. can be subclass):
Note that the above said "can't use full potential" due to it can't reach subclass-wide merely because no outer subclass, that's means actually protected can be allow, it's just a matter of choice to avoid duplicate the job of package-private if outer not subclass-able, see below.
As we can see now, both protected and package-private are the same level now (Y-Y-N), no more confusion about why in-between level is not allowed. Overall, Java pick only package-private over protected to avoid confusing(it's just a matter of choice, but protected main characteristic is subclass, so package-private is superior), and the result, only 2 access modifiers allowed in top-level:
Protected is not similar to public. Protected has both package level access plus can be accessed outside of packages only by inheritance..If a class say A outside a package INHERITS a class from other package(with protected method by using INHERITANCE) it can access the methods of this class B which has protected methods but the sub-classes derived from this class i.e., A can't access the protected methods..the opposite happens with public..
if a outer class is declared by protected, I think you want the class can be only accessed from same package and its subclass but different packages. However, there is no possible to create subclasses for a protected class, because when you write "class Dog extends Animal", because of protected "Animal" only can be accessed by its subclass, obviously, "Dog" is not "Animal" subclass.
The protected modifier is allowed on an inner class. But still an instance of this inner class cannot be constructed from within a class extending the outer class. Only when the constructing code is within the same package it is allowed by the compiler. But what difference does the protected modifier then make with respect to the default accessibility?So, from my point of view, the protected modifier is not at all allowed on top-level classes, and it does not make sense on embedded classes.
You can then apply the same logic to protected methods and variables, they are also then "similar to public". All classes outside of a package can extend our public class and use its protected methods. Why is restricting methods and variables to extended classes ok, but restricting the whole class not ok? "Similar to public" is not "same as public". My interpretation is that it is perfectly fine to allow a protected class, as it is fine to allow protected methods.
The answer why protected class will not be accessed by JVM is that, since protected fields are accessible within same package or to diffrent package through inheritance only and JVM is not written in a way so that it will inherit will class. Hope this satisfies this question :)
