A Proxy Pattern egy structural design that provide a placeholder or surrogate for another object.

Understanding the Proxy Ampantin
The Proxy Performn involves creating a proxy class that controls connecs to a real object. This proxy acts a stand-in, managing the creation and loading the heavy resource onlyy when requid. This approach h is known a lasy loadiring or deferred loading, whichh helps assents conservie system restaceand reduce startup time time.
Végrehajtása Lazy Loading in Desktop Applications
To implement the Proxy Pattern for lazy loading, follow these steps:

Example Scenario: Loading Large Images
A desktop application that displays a gallery of high- resolution images. Loading all imagees at startup cen slow and resource- intenzive. Instald, use the Proxy applicatioon to load each image only when the user views it.
