I need to convert my following Mage::getModel() from Magento1 to Magento2

$cart_api = Mage::getModel('checkout/cart_api');

$quoteId = $cart_api->create($storeObject->getStoreId());

$quote = Mage::getModel('sales/quote')->loadByIdWithoutStore($quoteId);



$product = Mage::getModel('catalog/product');



$customer = Mage::getModel('customer/customer');

$customerAddress = Mage::getModel('customer/address');



$convertQuoteObj = Mage::getModel('sales/convert_quote');



$storeObject = Mage::getModel('core/store')->load(1);

So anyone let me know the correct method for Magento2.

For Mage::getModel magento1 you need to use the below code for Magento 2:

$objectManager = MagentoFrameworkAppObjectManager::getInstance();

$model = $objectManager->create('NamespaceModulenameModelModulename');

For Mage::getSingleton you need to use:

$objectManager = MagentoFrameworkAppObjectManager::getInstance();

$model = $objectManager->get('NamespaceModulenameModelModulename');

Override constructor in your Model class and add your model class as dependency.

protected $_modelObj;

public function __construct(

    ...

    VendorExampleModelModel $modelObj,

    ...

) {

      ...

      $this->modelObj = $modelObj;

      ...

}



function someMetod() {

    $model =  $this->modelObj->create();

}

There are thousands of examples you can find in google for same. Also you can check core files how it is implemented.

Adding here one specific answer for your question:

protected $_quoteFactory;



public function __construct(

    ...

    MagentoQuoteModelQuoteFactory $quoteFactory

) {

    $this->_quoteFactory = $quoteFactory;

    parent::__construct(...);

}

Then in your class you can do:

$this->_quoteFactory->create()->loadByIdWithoutStore($quoteId);

For using it in your custom class, check this link!

Hope this helps!

<?php



namespace Yourcompany<yourmodule>Helper {



/**

 * Customer data helper

 */

class Data extends MagentoFrameworkAppHelperAbstractHelper

{

    protected $customerRepository;



    public function __construct(

        MagentoCustomerApiCustomerRepositoryInterfaceFactory $customerRepositoryFactory) {

        $this->customerRepository = $customerRepositoryFactory->create();

    }



    public LoadCustomerById($customerId) {

         $customer = $this->customerRepository->getById($customerId);

         return $customer;

    } 



}

Same way you can add functions for getting product detail and use these in your module controller. Hope this helps!
