Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    InputStream is = new FileInputStream("c:/test.txt");

    InputStreamReader isr = new InputStreamReader(is);

    BufferedReader br = new BufferedReader(isr);

    int value = 0;
    while ((value = br.read()) != -1) {
        char c = (char) value;
        System.out.println(c);//w  w w.  j a v a  2  s .co m
    }
}

From source file:Main.java

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

    BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
    String inputLine;/*w  w w  . ja  v a  2s  .  com*/

    while ((inputLine = in.readLine()) != null)
