Hello and welcome to discourse about design patterns in Java.

2
00:00:06,560 --> 00:00:12,800
The objective of this course is to introduce you to the most common design patterns that can be implemented

3
00:00:12,800 --> 00:00:13,490
in Java.

4
00:00:14,550 --> 00:00:20,250
And discourse, you learn everything you need to know about design patterns from each of the three main

5
00:00:20,250 --> 00:00:23,430
categories operational, structural and behavioral.

6
00:00:24,210 --> 00:00:25,970
But first, what is a design pattern?

7
00:00:26,910 --> 00:00:32,280
A design pattern can be thought of as a reasonable solution that can be applied to common programming

8
00:00:32,280 --> 00:00:37,100
scenarios, as a developer, you will encounter design patterns everywhere.

9
00:00:38,070 --> 00:00:44,430
The Java API alone solves most of its programming challenges with different design patterns, we can

10
00:00:44,520 --> 00:00:52,020
think of a design pattern as a solution to a common problem and also a framework that will make code

11
00:00:52,020 --> 00:00:53,250
easier to maintain.

12
00:00:56,230 --> 00:01:03,670
Last but not least, it provides more credibility for the code, so it makes it easier to read.

13
00:01:05,390 --> 00:01:08,990
The first category that we are going to discuss about is the creation of patters.

14
00:01:10,860 --> 00:01:17,100
These are issues to solve common problems when creating objects, so they are mostly concentrated on

15
00:01:17,100 --> 00:01:20,010
the creation aspect of your objects.

16
00:01:21,220 --> 00:01:24,850
They are also used to simplify the creation of complex objects.

17
00:01:30,260 --> 00:01:37,550
So having complex objects created in your code, it can pose a threat to the overall readability of

18
00:01:37,550 --> 00:01:44,600
your code, so those patterns will also improve the reliability of your code base.

19
00:01:47,130 --> 00:01:54,630
Types of regional powers are the builder pattern, the factory pattern, the abstract factory Singleton

20
00:01:54,930 --> 00:01:57,830
prototype and the object pool.

21
00:01:58,110 --> 00:02:02,850
So join me in the next section where we are going to discuss about each and every one.
