Java swing component instantiation

Recently while developing a swing application somebody told me to use (ComponentClassName) Beans.instantiate(MyClass.class.getClassLoader(), ComponentClassName.class.getName()) to create component object instead of using "new". I would like to know the right approach.

I think the right approach will be to use the new keyword, after all, that's it's role. The way you are using Beans seems a bit forced since you know what type of class you wish to instantiate. Second, since this is a swing application, most probably you are using default swing classes (maybe extending some of them). Another problem with this approach is that you must have a constructor without args in your class. Class.forName() can be used for the same thing as the code above, but if you don't want to dynamically create a class at runtime, stick with the new keyword.

You can use Beans.instantiate() if the type you want to instantiate is chosen dynamically. Generally the new keyword works just fine, and is what I always use in Swing applications.
