Does this java method close the inputstream after reading the file?
Files.readAllBytes(Paths.get("file"))
Yes, it closes. See it in the javadoc .
Reads all the bytes from a file. The method ensures that the file is closed when all bytes have been read or an I/O error, or other runtime exception, is thrown.
Note that this method is intended for simple cases where it is convenient to read all bytes into a byte array. It is not intended for reading in large files.
public static byte[] readAllBytes(Path path) throws IOException {
try (SeekableByteChannel sbc = Files.newByteChannel(path);
InputStream in = Channels.newInputStream(sbc)) {
long size = sbc.size();
if (size > (long)MAX_BUFFER_SIZE)
throw new OutOfMemoryError("Required array size too large");
return read(in, (int)size);
}
}
