Usage

From source file:Main.java

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

    int i;//www.  j a  v  a 2s  . c  o  m

    FileInputStream fis = new FileInputStream("C:/test.txt");
    InputStreamReader isr = new InputStreamReader(fis);

    while ((i = isr.read()) != -1) {
        char c = (char) i;
        System.out.println("Character read: " + c);
        // true if the next read is guaranteed
        boolean bool = isr.ready();

        System.out.println("Ready to read: " + bool);
    }
