Which is an example of an object instantiate?
Instantiate can be used to create new objects at runtime. Examples include objects used for projectiles, or particle systems for explosion effects. Instantiate can also clone script instances directly. The entire game object hierarchy will be cloned and the cloned script instance will be returned. // …other code… }
How to create and instantiate generic types in Java?
Call the MakeGenericType method to bind the type arguments to the type parameters and construct the type. Use the CreateInstance (Type) method overload to create an object of the constructed type. The following code stores two instances of the Example class in the resulting Dictionary object.
