class RawDemo {
    public static void main(String args[]) {
        Gen<Integer> iOb = new Gen<Integer>(88);

        Gen<String> strOb = new Gen<String>("Generics Test");

        Gen raw = new Gen(new Double(98.6));

        double d = (Double) raw.getob();
        System.out.println("value: " + d);

        strOb = raw; // OK, but potentially wrong
        raw = iOb; // OK, but potentially wrong
    }
