Java Forum / General / October 2007Call a class using its name (in String object)??
I have a name of a class in a string object. Is there a way to call that class using its name in a string object? I am using reflection and I have the name of the class; is there a way to call it using that name? Thanks > I have a name of a class in a string object.

You can load a class and instantiate it, its called Reflection. Don't use reflection! Well, don't use it unless you have a *REALLY* good reason to. <http://virtualinfinity.net/wordpress/program-design/2007/01/11/the- dangers-of-reflection-or-put-down-that-mirror/> Having said that, if you really want to know how, google for Java Reflection. You can load classes, instantiate objects, call methods, access fields, etc... -- Daniel Pitts' Tech Blog: <http://virtualinfinity.net/wordpress/> Free MagazinesGet these publications absolutely FREE for up to 12 months.
