class instantiation

The first question we have is, “What class are we instantiating?” If you’re not sure, it’s a good idea to check out the Quickstart Guide.

In class instantiation, the compiler must instantiate each method in the class, and then compile the entire class.

The compiler instantiates a class when it creates an instance of the class, which is why you should know all the things you need to know about the class before you can actually instantiate it. This includes the type of each variable, the length of each method, and the type of each parameter.

If you don’t know the type of each parameter, you can’t actually instantiate it (or at least, not properly). In case you didn’t know, the type of each parameter is the type of the variable (ex. if you wanted to pass a string to a method, you’d need to instantiate a string).

This is one of the most important rules for any OOP language. If you want to instantiate the same object more than once, you cant. The only way to do this is to make a variable of the same type. Even if you dont want to use the variable, you cannot make the variable of the same type. For instance, if you wanted to instantiate an object of type Date, youd have to instantiate a Date.

The problem with this rule is if you want to instantiate an object more than once, you must instantiate a different object. This rule works great in practice, but may be limiting. A common OOP practice is to make the variable of the same type as the object. In this case youd need to make the variable of the same type as the object.

But what if you want to instantiate an object of type Date but it is not the same type as the object you are instantiating? For instance, youd want to instantiate a Date object that is a subclass of Date. Since Date is an object of type Date, and Date is not a subclass of Date, youd need to instantiate a new Date object.

The problem with this is that it makes code harder to read and maintain. In general, youd want to make the variable of the same type as the object. But what if you want to instantiate an object of type Date but it is not the same type as the object you are instantiating? Or, for that matter, what if you want to instantiate a class, but it is not the same class as the object you are instantiating.

Again, an instance is a type of object. And in the case of Date, it is the same type as the object. So youd need to instantiate a new Date. But what if you also want to make a new Date from a Date. Also, Date’s methods aren’t class methods, so youd have to implement them manually.

The class instantiation is something that is almost as common for Java as it is for C++. You can’t really easily instantiate the same class and have it compile with different methods, so you’d have to duplicate the methods. But you could easily instantiate a Date with a different method and have a separate class Date. But this would still leave you with the same Date with its original method, not a new Date.
