An intermediate course in Java typically covers more advanced concepts and techniques beyond the basics of the language. Here are some common topics that might be included:

Object-Oriented Programming (OOP) Principles: Deeper understanding of inheritance, polymorphism, abstraction, and encapsulation. This may include advanced usage of interfaces and abstract classes.

Data Structures and Algorithms: Implementation and usage of data structures like linked lists, stacks, queues, trees, and hash maps. Algorithmic concepts such as sorting, searching, and recursion are also often covered.

Exception Handling: Advanced techniques for handling errors and exceptions, including custom exception classes and best practices for robust error handling.
