Core Java Programming Course- Tree Map

This video tutorial explains the concept of a treemap, highlighting its similarities and differences with a hashmap. It covers the implementation of a treemap using a red-black tree structure, ensuring entries are sorted by keys. The tutorial discusses common methods shared with hashmap and unique methods specific to treemap, such as retrieving the first and last entries. Practical examples demonstrate how to use these methods, including advanced techniques like pole first and last entry, which retrieve and remove entries simultaneously.

Describe the methods that are common between treemap and hashmap.

What are the unique methods available in a treemap that are not found in a hashmap?

What does the 'contains value' method do in the context of a treemap?

Explain how the 'replace' method works in a treemap.

What is the significance of the order in which entries are stored in a treemap?

How does the 'poll first entry' method function in a treemap?
