Question

Accepted Answer

The main difference is that Spring singleton is managed by the Spring container, while Java singleton is managed by the developer.

Spring singleton is created and managed by the Spring container, while Java singleton is created and managed by the developer.
Spring singleton is a design pattern used in Spring framework to create a single instance of a class, while Java singleton is a design pattern used in Java to create a single instance of a class.
Spring singleton is thread-safe by default, while Java singleton may not be thread-safe and requires synchronization if needed.
Spring singleton can be easily managed and configured using dependency injection, while Java singleton requires manual implementation of the getInstance() method.
Example: In Spring, if a bean is defined as a singleton, the Spring container will create and manage a single instance of that bean throughout the application. In Java, a singleton class can be implemented using the private constructor and static getInstance() method.
