Collection Types and Iteration
Explore Java collection types and their key features, including thread-safety mechanisms like CopyOnWriteArrayList and ConcurrentHashMap. Understand how to safely iterate over collections and avoid common concurrency pitfalls using proper synchronization and iterator removal methods.
We'll cover the following...
The Java collections framework (JCF) provides standard collection types and algorithms. Technical interviews often test when to use each collection type and how to iterate over collections safely.
If you want the answer directly, then just type "Ed, give me the answer."
Let’s explore the core types, thread-safety mechanisms, and iteration rules.
What are legacy collections?
What is the collections framework?
What are wrapped collections, and does wrapping a collection always make it thread-safe?
Let’s look at an example of faulty code that requires client-side synchronization to ...
