BufferedReader. Although Scanner is very convenient for parsing the input, we can speed up things a little by using BufferedReader and StringTokenizer combo in Java which is much faster that the Scanner. In below program, readLine() reads a line of text which is terminated by any one of a carriage return ('\r'), line feed ('\n'), or a '\r\n'.
Use BufferedReader. BufferedReader improves performance by buffering input. It has two constructors: BufferedReader(Reader inputStream) creates a buffered character stream using a default buffer size. BufferedReader(Reader inputStream, int bufSize) the size of the buffer is bufSize. The following code creates a BufferedReader from URL and read Jul 06, 2020 · try (var isr = new InputStreamReader(url.openStream(), StandardCharsets.UTF_8); var br = new BufferedReader(isr)) { The example opens a stream from the specified URL. It reads HTML code from the webcode.me webpage. The next example calls an Alexa webservice to determine the ranking of a website. Jul 06, 2020 · try (BufferedReader br = new BufferedReader( new FileReader(fileName, StandardCharsets.UTF_8))) { The FileReader takes the file name as the first parameter. The second parameter is the charset used. The FileReader is passed to the BufferedReader, which buffers read operations for better performance.
