![]() ![]() The default buffer size is 8Kb( which is enough in most cases) though it can be customized. Whereas BufferedReader creates an input buffer and allows the input to be read from the hard drive in large chunks of data rather than a byte at a time, resulting in a huge improvement in performance. Each time, it reads a character, it directly accesses the disk drive and every time it takes some time for the disk drive to position the read head correctly which makes it very inefficient. FileReader directly reads the data from the character stream that originates from a file. Usually, we wrap a FileReader with BufferedReader to read characters from files.īufferedReader is much more efficient than FileReader in terms of performance. Whereas, FileReader is capable of reading characters from files only. It creates a new BufferedReader with the given sized input buffer.Īs seen, BufferedReader accepts any type of Reader( StringReader, FileReader, etc.) and hence capable of reading from any character input stream. First: A Reader that is used to read the input stream data.BufferedReader(Reader rd, int size): Takes two parameters:.BufferedReader(Reader rd): It uses a Reader to read data from the character input stream and creates a default sized input buffer.FileReader(String fileName): Takes the name of the file as the only parameter and creates a new FileReader instance to read the file.īufferedReader class provides two constructors:.FileReader(FileDescriptor fd) : Creates a new FileReader, given the FileDescriptor to read from.FileReader(File file): It takes a File object that represents a file in your disk and creates a new FileReader instance.FileReader class provides two constructors: It can be used to read data from any character stream.
