Getting Started With Data Structures
Get started with an overview of data structures, algorithms, and dig into building your first data structure!
Linear Data Structures
Learn to build various linear abstract data types in Java, such as linked lists, queues, and stacks.
Learn hash maps, a key-value data storage structure with very efficient lookup performance.
Learn algorithm fundamentals, including recursive vs. iterative patterns and Big O asymptotic notation.
Nonlinear Data Structures
A conceptual and Java-specific introduction to Trees, Binary Search Trees, and Heaps.
Learn about sorting algorithms in Java.
Graph Data Structures
Learn to build a Graph in Java, and then traverse it using depth-first search, breadth-first search, and Dijkstra’s algorithm.
Hands-on learningDon't just watch or read about someone else coding — write your own code live in our online, interactive platform. You'll even get AI-driven recommendations on what you need to review to help keep you on track.
