Usage

From source file:Main.java

public static void main(String[] args) throws Exception {

    InputStream inStream = new FileInputStream("c:/test.txt");

    BufferedInputStream bis = new BufferedInputStream(inStream);

    // read until a single byte is available
    while (bis.available() > 0) {
        // get the number of bytes available
        Integer nBytes = bis.available();
        System.out.println("Available bytes = " + nBytes);

        // read next available character
        char ch = (char) bis.read();

        // print the read character.
        System.out.println("The character read = " + ch);
    }/* w  w  w  . java 2 s .co m*/
