Usage

From source file:Main.java

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

    Reader r = new StringReader("ABCDEF");

    // create new filter reader
    FilterReader fr = new FilterReader(r) {
    };// w ww  .j av a2 s .  com

    // true if the filter reader is ready to be read
    boolean bool = fr.ready();

    // prints
