FAQs on 11 - Singleton Sets Video Lecture - Sets and Functions - JEE
| 1. What is a singleton set? |  |
Ans. A singleton set is a set that contains only one element. In other words, it is a set with a cardinality of one.
| 2. How does JEE handle singleton sets? | |
Ans. In JEE (Java Enterprise Edition), singleton sets can be implemented using the Singleton design pattern. This pattern ensures that only one instance of a class is created and provides a global point of access to it.
| 3. What is the significance of using singleton sets in JEE? | |
Ans. Singleton sets in JEE are commonly used to manage shared resources, such as database connections or thread pools, where only one instance of the resource is needed throughout the application. It helps in efficient resource utilization and reduces the overhead of creating multiple instances.
| 4. Can a singleton set be modified in JEE? | |
Ans. In JEE, the Singleton design pattern restricts the modification of the singleton set once it is created. This is to ensure that the global state of the application remains consistent and avoids the possibility of concurrent modifications leading to inconsistent behavior.
| 5. How can a singleton set be accessed in JEE? | |
Ans. In JEE, a singleton set can be accessed using a global point of access, typically provided by a static method in the singleton class. This allows other parts of the application to obtain the instance of the singleton set and access its methods and properties.
