Java Tutorial #60 - Java Sorted Map Interface with Examples (Map Data Structure)
In this video by Programming for Beginners we will learn Java SortedMap Interface with Examples (Map Data Structure), using Java Tutorial videos.
The SortedMap interface of the Java collections framework provides sorting of keys stored in a map.
It extends the Map interface.
Since SortedMap is an interface, we cannot create objects from it.
In order to use the functionalities of the SortedMap interface, we need to use the class TreeMap that implements it.
Methods:
comparator() - returns a comparator that can be used to order keys in a map
firstKey() - returns the first key of the sorted map
lastKey() - returns the last key of the sorted map
Map Methods:
put(K, V) method
putAll() method
putIfAbsent(K, V) method
get(K) method
keySet() method
values() method
entrySet() method
==========
We can learn Java Programming language to make web applications or mobile applications for android phones and several other applications for windows, Mac OS and Unix operating systems. Also we can make android applications using Java programming. The concepts covered will be related to basic java and core java that will help you in your next interview questions. You can use any version of Java but all concepts will be same for all java versions. I will be using Java SE 8.
Java is a high-level programming language. Java runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX.
Java is a MUST for students and working professionals to become a great Software Engineer specially when they are working in Software Development Domain.
