What Will I Learn?
Master modern Java with a focused, hands-on course that teaches you to design safe, immutable domain models and robust APIs. Learn Java 11 features, collections with generics, null-safety, and Optional, then build solid value types like Money, Orders, and OrderItems. Practice clear exception handling, discount strategies, equality, hashing, and testing so your code stays reliable, maintainable, and easy to extend.
