(Lesson 3) Array instantiation / initializing confusion...

[Brentably]

This is the code I'm looking at now. It runs fine. I just have a question about instantiating new variables in this language.

`//SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "./NewSolution.sol";

contract StorageFactory {

NewSolution[] public storageArray;

function deployStorageSolution() public {
    NewSolution storageSolution = new NewSolution();
    storageArray.push(storageSolution);
}

}`

So when you import NewSolution.sol, you're basically importing a contract, which is an object. This is fine. When you write NewSolution[] public storageArray You are initializing a new array called storageArray with data type set to that contract object? But I also notice you can use the new keyword to create a new NewSolution object, so basically you can create arrays out of any object? Can you use the new keyword on any object?

@Brentably

1. When you specify the import statement it means we can use that contract inside that contract. It is called importing a contract.
2. NewSolution[] public storageArray; This is the declaration of an array variable that type is of that contract (in this case).
3. NewSolution storageSolution = new NewSolution(); This is called the initialization of a contract and the whole line is called an object.

Hope it clears your questions.
