Yes. Look up java.lang.Class and its forName() method.

If it has a constructor that doesn't need arguments, then you can simply
do:

Class.forName("com.mypack.MyClass").newInstance();

If you wish to use a constructor that does require arguments, then
you'll have to call getConstructor on the Class instance, and then call
Constructor's newInstance method.
