FileInputStream
or FileOutputStream
constructors when it is possible to replace
them with Files.newInputStream()
or Files.newOutputStream()
accordingly.
Files
methods are usually more efficient than those created by stream constructors.
Example:
InputStream is = new BufferedInputStream(new FileInputStream(file));
After the quick-fix is applied:
InputStream is = new BufferedInputStream(Files.newInputStream(file.toPath()));
This inspection does not show warning if the language level 10 or higher, but the quick-fix is still available.
This inspection only reports if the language level of the project or module is 7 or higher.
