Designing Object Oriented software systems is hard and designing reusable object oriented software is even harder. One must find pertinent objects, factor them into classes at right granularity, define class interfaces and inheritance hierarchies and establish key relationships among them.
Experienced Object Oriented Designers, over a period of software design have noticed while designing any software system(irrespective of domain) some of the design scenarios recur multiple times. So they have come up with standardized object oriented solutions for these recurring design scenarios and called them Design Patterns (Elements of reusable Object Oriented Software).
Why Design Patterns
Coding is not enough: Many of the times code fixes are not going to yield solutions when there is fundamental problem in software design.
Design helps us to get big picture of software system: No matter how good are we in programming language (C++, Java, C#, Python, Ruby..), unless we have design skills it is impossible to understand whole software system in relatively short duration of time.
This is the way ahead for software developers in career: Any engineer passed out of engineering college, starts career as developer or programmer for 2...3 years Then what is next? Next step is to take part in software system design process.
More than 80% of the modern software systems are object oriented: Therefore "design patterns" is very widely applicable and heavily valuable skill to have for any software developer.
Design Patterns are domain agnostic: Same across different application and system domains( Telecom, Finance, Banking, Insurance, Transport, Online Shops, Networks,...)
Design Patterns questions have been asked in almost all product and Technology companies for 2+ years experience candidates.

Emphasis is put on immediate feedback and on having a fun experience. Programming knowledge is not only useful to be able to program today’s devices such as computers and smartphones. It also opens the door to computational thinking, i.e. the application of computing techniques to every-day processes.
Java is a compiled and interpreted language, python is a interpreted scripting language.
Java runs significantly faster than python.
Java runs on a variety of devices such as a mobile, a smart card, the mars rover, computers, may be even that harmless toaster sitting in one corner of your kitchen too.
For most courses, exam fees are separate. However, we do offer Exam Deals and Pro Packs which include the cost of official certification exam fees, for a huge cost savings. Pro Packs also include relevant of Live Labs.

E-learning is a medium for engaging learners in an online training course. E-learning courses can exist in many forms, using different types of technologies. Commonly used in organizations and corporations, e-learning can help learners complete training and education objectives with ease and flexibility as compared to traditional classroom-based learning.
