We can get attribute data by attribute code by just passing the attribute code in Magento 2.

We have taken entity_type_code  value as Catalog_Product  for a demo in the below code, You can get any entity_type_code as per your requirement.

<?php

public function __construct(
    \Magento\Eav\Model\Entity\Attribute $entityAttribute
) {
    $this->entityAttribute = $entityAttribute;
}

/**
* Load attribute data by code
* @return  \Magento\Eav\Model\Entity\Attribute
*/
public function getAttributeInfo($attributeCode)

Get Product qty or stock information by Product Object is pretty easy in Magento 2.

We can simply get product qty from the product id and get the first product object. We can get product data from either by id or by SKU.

Please check below code snippet for getting product qty in Magento 2,

        \Magento\CatalogInventory\Model\Stock\StockItemRepository $stockItemRepository,
        array $data = []
    ) {
        $this->stockItemRepository = $stockItemRepository;
        parent::__construct($context, $data);
    }
