The Most Important Java topics that can never be missed prior to an interview.
The first one is Java Features - Any programming language you pick up, you must know in and out about it to stand out from the rest and ace your interview… Hence, the very first thing is to learn about the details such as what are the benefits of java over other programming languages, about JDK, JRE, JVM and ultimately give a reason for choosing your favourite language as java.
The Second one is Java OOPS: In the fast growing paced world, using technology in a right style matters the most, so one of a highly used programming style is Oops (Object Oriented Programming) and learning about features of oops, how can oops amplify the application, can help you grab your seat at the company.
The third one is Data Structures: For you to be a great developer you need to master data structures, and have solid understanding on which scenario can a particular data structure be used. This will also polish your programming and software development skills.
The Forth one is Algorithms: Running a solution without a base plan makes no sense, so it is crucial and necessary to put down your solution in steps and analyse the approach in terms of time and space efficiency, post which if things look better move on with the development. If not, look for another better approach.
The Fifth one is BIG O notations: To consider if an algorithm is efficient and decide the acceptance or rejection of the algorithm purely lies on the BIG O analysis. so having a clear understanding of BIGO can increase the chances of your selection.
And the last one in Java advance concepts and Frameworks: It is always a benefit to know more about what you pick, so having knowledge about advanced java topics or framework such as spring, hibernate can always be a master stroke for you and can keep doors open.
That's all for today.
