- 👋 Hi, I’m @ZhianMai, and go by Johnston. Contact me @ johnstonmai11@gmail.com
- 👀 I’m interested in problem solving and Java-related skills like Spring Framework and Java multithreading.
- All these challenges can make me excited: binary search, binary tree, BST, DFS, BFS, DP... you name it!
- My coding strictly follows Google Java style guide, SOLID principle, concepts from Effective Java, and industry standard if appliable.
Check out the repos below as my sample coding works here :)

Thread-safe Linked-list & Hash Map in Java 🔗link
@author Zhian Mai
Size: ⭐⭐⭐
Complexity: ⭐⭐⭐
Implementations of thread-safe linked-list & hash map using read-write lock, with multi-threaded testing.
Highlights:
- Support generic;
- Support Iterable<>;
- Factory pattern to create hash map, based on thread-safe stragegy (no thread-safety, synchronized, and read-write lock);
- Read-write lock provided by ReentrantReadWriteLock;
- Multi-threaded testing guarantees no data racing on thread-safety data structure;
- Java design rules from Effective Java;
- And more on the way...
