Lazy loading and eager loading in Java in context of Singleton class

Question

Accepted Answer

Lazy loading defers the initialization of an object until it is actually needed, while eager loading initializes the object immediately.

Lazy loading is commonly used in Singleton pattern to delay the creation of the instance until it is requested.
Eager loading initializes the Singleton instance at the time of class loading.
Lazy loading can help improve performance by only creating the instance when needed, while eager loading can lead to higher memory consumption.
Example: Lazy loading in Singleton can be achieved by using a synchronized getInstance() method to create the instance only when it is called.
Example: Eager loading in Singleton can be achieved by directly initializing the instance when the class is loaded.
