Lab Exercise $1$: Describe a Component Class Design where the Singleton Pattern can be applied Please develop UML Diagrams and write code in Java. While working on the design of a smart alarm production system simulator, you found that the class SmartAlarmProducer is required to have only one instance. Singleton Pattern is an appropriate design pattern to address this situation. Develop an UML class diagram to show the use of the design pattern in the current context. Write a Java program to implement the class SmartAlarmProducer. The program can be small enough to merely illustrate the concept of the Singleton Pattern.
