From 0 to 1 Data Structures & Algorithms in Java - Building A Stack Using Java

The video tutorial covers the implementation of a stack using a linked list in Java, emphasizing the use of generics for flexibility. It explains stack operations like push, pop, and peek, and discusses handling exceptions such as stack overflow and underflow. The tutorial also analyzes the performance and complexity of stack operations, highlighting the benefits of using a size variable for constant time complexity. Finally, it explores real-world applications of stacks, including undo functionality, web browser navigation, recursion, and expression evaluation.
