Can we create multiple objects same class?
We can create multiple objects by one type only as we do in case of primitives.
Is it possible to create multiple objects from the same constructor?
You can declare multiple variables on the same line. However, it is generally a good idea to declare no more than three variables on the same line. Each variable will then require it’s own instantiation, which could either be to three different objects of the same type or to the same object.
Can you create multiple objects with the same name in Java?
The two constructors with different parameters are simply used to initialize the fields in the object. An object is an instance of a class and everything in the class is part of the same object. It is possible to have multiple methods and multiple constructors with the same name.
How do you create a new object?
Creating an Object
- Declaration − A variable declaration with a variable name with an object type.
- Instantiation − The ‘new’ keyword is used to create the object.
- Initialization − The ‘new’ keyword is followed by a call to a constructor. This call initializes the new object.
How do you make more than one object refer to the same object?
11. How to make more than one object refer to the same object? Explanation: The object must get initialized with another object at time of declaration only. We don’t have to create a new object we just have to get name of new object because there after same address will be referred.
Can we create multiple objects of same name?
Yes, it can. However, there can only be one public class per . java file, as public classes must have the same name as the source file. One Java file can consist of multiple classes with the restriction that only one of them can be public.
Can class and object have same name?
A companion object is an object that’s declared in the same file as a class , and has the same name as the class. A companion object and its class can access each other’s private members. A companion object’s apply method lets you create new instances of a class without using the new keyword.
How do you create multiple objects in Javascript?
It is very easy to create a single object than to create multiple objects of the same type. To breach this hurdle, javascript has provided object constructor function. Using this function, initially, we have to create the type of the object and later on, we need to declare the properties of the object.
How to assign to object number in object initializer?
This means you have to use i + 1to assign to the object number, or the objects would be numbered 0 – 9, just like their indexes in the array. I’m initializing the objects using object initializer syntax, which is new in C# 3.0.
Does user[I] = new user create an object of user?
Many think that the statement, User user [i] = new User (), creates an object of User, but it creates a reference variable. Conversion of reference variable into object is required as follows: This you can find more in Confusion of reference variables and objects in arrays (array of array objects)
Are variables in an object always the same type?
The variables in the object are always the same type but i need to name them properly so I can effectivly write methods to perform operations on them in a later phase of the program. Im just learning the language and I would be very thankful for a advice on how to approach my problem. c# Share Improve this question Follow
Why not make a list of OBJS variable names?
The answer is: keep your data out of your variable names, and this is the obligatory blog post. In this case, why not make a list of objs? you can use list to define it. Creating a dictionary as it has mentioned, but in this case each key has the name of the object name that you want to create.
