Android singleton class in java Before going into an example, we need to be aware of what a singleton design pattern is. A singleton is a pattern that limits the creation of a class only to one instance. It is useful for managing concurrency as well as making a central point of access for applications in order to connect with its database storage.

In object-oriented programming, the singleton class is one that can only have an object (an instance) at one time. After the first attempt, if we attempt to create this Singleton class then, that newly created variable is also pointing to the initial instance that was created. Therefore, any modifications made to any variable in the class, in any way alters the variable for the single instance created. This can be seen if we try to connect to that variable using any variable belonging to the class type.
