You want to create a singleton class by using the Singleton design pattern.
Which two statements enforce the singleton nature of the design? (Choose two.)
To enforce the singleton nature of a design, the constructor of the class should be made private to prevent instantiation from outside the class. Additionally, the single instance of the class should be made static and final to ensure that exactly one instance of the class is created and it is globally accessible. These steps ensure that the singleton pattern is correctly implemented and adhered to.
