Answer / Mr Praveen Kumar Jain
A static class in Java serves the following purposes:
1. Static classes can contain only static members (methods and variables). This means they do not need an instance of the class to be created before using them.
2. They are often used for utility or helper classes that provide functionality without requiring object creation.
3. Static classes are useful when you want to ensure that only one instance of a particular class can exist within a Java Virtual Machine (JVM).
