Can you explain what it means to explicitly use Intent in Android?

Explicit use of Intent in Android means that you explicitly specify the component (for example, Activity or Service) that should be started. This is done by setting the class name of the component in the Intent. This approach guarantees that the specified component will be called, without the system searching for suitable handlers.

Example of an explicit Intent to start an Activity:

Intent intent = new Intent(this, TargetActivity.class);
startActivity(intent);

Unlike implicit Intent, where you specify an action or category and the system chooses the appropriate component, explicit Intent is used for direct interaction within your application or between known components.
