Java and Optional – In Depth

This is an in-depth look a truly fundamental concept in Java programming – and how Optional, if used properly can address many of the issues associated with. Some of the questions I hope to answer include: Is a bad concept or is the implementation that’s the problem?How to prevent NullPointerExceptions?How and when should Optional be used?What are the alternatives to Optional?What are some key design considerations in regards to in my application?What are other fundamental concepts such the Object Pattern etc?How do some other languages handle? I hope that by the end of the course you will have a solid understanding of what really is so you can design and develop your applications with confidence. I want to remove those nagging doubts you may have about. I’m hopeful that you will have a really strong understanding of how Javas Optional can help to deal with some of the issues surrounding and also understand how it interplays with Streams. This is often what causes a lot of the confusion. However by understanding a few core concepts I believe this can be a thing of the past and you can use these tools in the best way possible.
