Anyone have idea about declare class in __construct and declare class in top of file with use.

Exemple:

use MagentoStoreModelStoreManagerInterface;

and

Passing the full name space directly in the constructor is straightforward and easy.

All in one place, you do not have to scroll up to figure out what has just arrived at your constructor.

The use statement has one nice feature that allows aliases like

use MagentoStoreModelStoreManagerInterface as TheStorageInterface

and your refer to this type by its alias like

public function __construct(
 TheStorageInterface $theStorage,
) 
 $this->_storeManager = $theStorage;

Yes, you could type just about anything, but usually this is the name of the class/interface.

One thing to notice: if you need to inject the StoreManagerInterfaceonce only once per class, just like magento usually does with constructor injection, it really does not make much difference.

But if you would need to inject twice or more times, for example in two different methods, than maybe the alias usage is better.

Eventually, there is no right or wrong. It is just a matter of taste, or, you simply have no choice but to follow what has been established as a practice in a given project.

And no, I would never give such a name for the alias (TheStorageInterface) in a real program :)

public function __construct(

 $this->_storeManager = $storeManager;

and if you not define the class in top then you can also managed it by injecting directly in your __construct function like below:

Both are same.
