The one programming language that triumphs all is Java. No matter what development project you’re working on, Java works as the server-side language for almost all back-end tasks, from games to mobile computing and numerical computing. No wonder it’s used by more than 9 million developers.
If you’re planning to begin your career in Java programming, your prospective employer will be interested in asking a plethora of questions. These questions won’t just be limited to your knowledge of Java but also about its technicalities.
Read some questions by Pritish Kumar you should know the answer to.

1. What is Java Class?
When it comes to the core elements of this language, a good Java developer will know it. Remember to be concise while showing you have an understanding of the elements.
Answer: “The Java class represents a category of the objects that consist of similar properties or methods. It works as an integral blueprint while designing an object-oriented program.”
2. What are some of the common classes in Java?
Again, it’s a continuation of the previous question that seeks to understand the extent of your Java knowledge. The key here is to use simple language while answering as precisely as possible. However, if the manager is interested in knowing how you use it in your work, be as detailed as possible.
Answer: “There are multiple classes in Java. The elementary classes include static, final, abstract, concrete, POJO, and inner. If you want, I can elaborate further on how I use them during app development.”
3. If we ask you to train an intern in Java, what would you teach them about wrapper classes?
This question aims to assess your technical grasp of Java, along with your interpersonal skills and how you share information with others.
Answer: “If I were in charge of training an intern about wrapper classes, I’d begin by first ensuring they have keen knowledge about all eight primitive types and how each can be used. Then I’d convey that allotting a wrapper class is immutable and final. When a person is aware of this, it saves them much time.”
