Usage

From source file:Main.java

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

    int i = 0;/*from w ww  .  j av  a 2  s .  c  om*/
    // create new file input stream
    FileInputStream fis = new FileInputStream("C://test.txt");

    // read till the end of the file
    while ((i = fis.read()) != -1) {
        // converts integer to character
        char c = (char) i;
        System.out.print(c);
    }
