Introduction

1. Java TreeMap sort key value pair by key value
2. Java TreeMap create with custom comparator for custom object
3. Java TreeMap sort last name then first name via custom comparator
4. Java TreeMap get head sub map by key value
5. Java TreeMap get sorted key one by one
6. Java TreeMap get sub map by key value range
7. Java TreeMap get tail sub map by key value
8. Java TreeMap merge case insensitive String key values via String.CASE_INSENSITIVE_ORDER



9. Java TreeMap sort by value not key
