While(!(line = bufferedReader.readLine()). InputStreamReader inputStreamReader = new InputStreamReader(System.in) // A stream for reading from the consoleīufferedReader bufferedReader = new BufferedReader(inputStreamReader) // Connect InputStreamReader to a BufferedReader We read data from the console and write it to a file: The buffer will write data internally, and then later write large chunks of files to disk.
Every time we access it, the buffer wrapped around it speeds up our application.

Here's an example of using the BufferedReader and BufferedWriter classes:Reading a file:įileReader fileReader = new FileReader(file) // A stream that connects to the text fileīufferedReader bufferedReader = new BufferedReader(fileReader) // Connect the FileReader to the BufferedReader Int read(char cbuf, int off, int len) // Read the bufferīoolean ready() // Is the stream ready to read?

You can pass the buffer size to the constructor as a second argument.īufferedReader(Reader in) // Creates a buffered stream for reading symbols. Java’s BufferedReader class reads text from a stream of symbols, buffering the symbols to efficiently read characters, arrays, and strings.
