I Have Loaded A Simple Product Using
MagentoCatalogModelProductRepository And Changed Its Quantity To 1 And Stock Status (is_in_stock) To 0,

Using Function $productStock->setQuantityAndStockStatus(['qty' => $correctedStock, 'is_in_stock' => $isInStock]);

After This Am Not Able To Load The Product Programmatically , It Shows Following Error.

`1 exception(s):
Exception #0 (MagentoFrameworkExceptionNoSuchEntityException): Requested product doesn't exist

Using Magento CE 2.1.2

Go to admin > Stores > configuration > Catalog > Inventory > Stock Options

Set Display Out of Stock Products to NO

You can create a Helper class (as given below ) to update product inventory as you want .

Assume you are using a custom extension Company_MyModule

<?php
namespace CompanyMyModuleHelper;

use MagentoFrameworkAppFilesystemDirectoryList;

class Data extends MagentoFrameworkAppHelperAbstractHelper


 /**
 * @var MagentoCatalogApiProductRepositoryInterface
 */
 protected $_productRepository;

 /**
 * @var MagentoCatalogInventoryApiStockStateInterface 
 */
 protected $_stockStateInterface;

 /**
 * @var MagentoCatalogInventoryApiStockRegistryInterface 
 */
 protected $_stockRegistry;



 /**
 * @param MagentoFrameworkAppHelperContext $context
 * @param MagentoCatalogApiProductRepositoryInterface $productRepository
 * @param MagentoCatalogInventoryApiStockStateInterface $stockStateInterface,
 * @param MagentoCatalogInventoryApiStockRegistryInterface $stockRegistry
 */
 public function __construct(
 MagentoFrameworkAppHelperContext $context,
 MagentoCatalogApiProductRepositoryInterface $productRepository,
 MagentoCatalogInventoryApiStockStateInterface $stockStateInterface,
 MagentoCatalogInventoryApiStockRegistryInterface $stockRegistry 
 ) 
 $this->_productRepository = $productRepository;
 $this->_stockStateInterface = $stockStateInterface;
 $this->_stockRegistry = $stockRegistry; 
 parent::__construct($context);
 

 /**
 * For Update stock of product
 * @param int $productId which stock you want to update
 * @param array $stockData your updated data
 * @return void 
 */
 public function updateProductStock($productId,$stockData) 
 $product = $this->_productRepository->getById($productId); //load product which you want to update stock
 $productSku = $product->getSku();
 $stockItem = $this->_stockRegistry->getStockItemBySku($productSku); // load stock of that product by SKU 
 $stockItem->setIsInStock($stockData['is_in_stock']); //set updated data as your requirement
 $stockItem->setQty($stockData['qty']); //set updated quantity 
 $stockItem->setManageStock($stockData['manage_stock']); 
 $this->_stockRegistry->updateStockItemBySku($productSku,$stockItem);
