How can I check a class has no arguments constructor

    Object obj = new Object();
    try {
        obj.getClass().getConstructor();
    } catch (SecurityException e) {
        e.printStackTrace();
    } catch (NoSuchMethodException e) {
        dosomething();          
        e.printStackTrace();
    }

I don't want check like this, because it throw a Exception.

Is there another way?
