 ### System Capabilities and APIs
 
-SystemCapability (SysCap in short) refers to a standalone feature in the operating system, for example, Bluetooth, Wi-Fi, NFC, or camera. Each SysCap corresponds to a set of APIs, whose availability depends on the support of the target device. Such a set of APIs can be provided in DevEco Studio for association.

 - Method 2: Import a module using the **import** API. If the current device does not support the module, the import result is **undefined**. Before using an API, you must make sure the API is available.
