Usage

From source file:Main.java

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

    int i;/*  w w w .jav a2s .c o m*/

    InputStream is = new FileInputStream("C://test.txt");

    while ((i = is.read()) != -1) {
        // converts int to char
        char c = (char) i;

        System.out.println("Character Read: " + c);

        // skip one byte
