A read-only file is any file with the read-only attribute. Read-only files can be opened and accessed but you will not be able to make changes to it. You can make a file read-only by using setReadOnly() method and can check this using canWrite() method of File class. If the value return from the canWrite() method is false, means that file is in read only mode and you cannot modify it.
Here is the code:
Code to check read only file:
Java API provides the functions to find if any file is read only.
The boolean b = file.canWrite(); function is used.
I returns true if file is not ready only else returns false.
If you are facing any programming issue, such as compilation errors or not able to find the code you are looking for.
