You can do this using this code:

Class clazz = Class.forName(yourString);

As the class name you should use the full class name including packages. But you can't call a class. You can initialize a class and then call a method of this class.

Learn reflection. By reflection you can get class by its name.

You can use Class.forName(className). See Java API.

    public static void main(String[] args) throws ClassNotFoundException {
        Class test = Class.forName("FooBar");
    }
