Data structure and algorithm in Java ( questions)Īpart from these topics, you could also take help from books like Java interview exposed and the Cracking the coding interview.

Abstract class and interface ( questions).

Java Collections Framework ( questions).

Date type conversion and fundamentals ( questions).

Multithreading, concurrency, and thread basics ( questions).

Data Structure and Algorithms ( questions).

Nevertheless, here is the list of topics I suggest to any Java developer who is serious about interviews.

Similarly, for an Android developer, apart from knowledge of Java fundamentals, knowing Android API is more important. Similarly, if you are going to work for a Java Web Service application then preparing about REST and SOAP, XML, JSON, and other relevant topics.įor Java, web application developers, JSP, Servlet, Spring, and Hibernate are more critical than multi-threading and JVM internals. Another thing that decides which topic you should prepare for your interview is the Job description.Īlso, there is no better guide than the Job description to prepare for relevant topics.įor example, if you are going to work for a core Java multi-threading based application, then you should prepare well for core Java topics like multithreading and concurrency, Java Collections, Generics, Enum, GC Algorithms, and JVM internals. I would ask more questions from Java fundamentals like String, Collections, equals() and hashcode and OOP concept to a fresher or Junior Java developers of 2 years experience, but those topics will be too trivial for Java developer of 4 to 5 years experience.įor those, I prefer to ask Concurrency, JVM internals, Garbage Collection, testing, and design patterns. Which Topics to Prepare for Java Interviews?Īs I told you, the importance of topics depends upon the candidate's experience. The best way to prepare for Java interviews is to join a course like Java Interview Guide: 200+ Interview Questions and Answers, though there is no substitute for the experience you can still manage to sail through by carefully preparing for your Java interviews. So your preparation should be aligned with your experience and not just focused on common programming questions.Īlso, Java EE interviews are totally different than core Java interviews because core Java interviews are mostly focused on core Java concepts like Concurrency, Collections, and JVM internals, while Java EE interviews are based upon a framework like JSF, Spring, Hibernate, and others. More senior developers like Java programmers with 5 to 6 years of experience will find more questions on concurrent programming, Java concurrency API, JVM internals, GC tuning, and Java Performance. For example, junior developers with 1 to 2 or 3 to 4 years of experience will see more questions on topics like Java fundamentals, API, data structure, and algorithms. Since Java is primarily used as an application programming language, the focus is aligned accordingly with questions mostly focusing on API, Java concepts, and design patterns.Īlso, Java interviews change a lot depending upon the candidate's experience. Since Java is also an Object-oriented programming language, you will find lots of OOP questions there. Another essential thing about Java interviews are questions based upon Java programming language and JDK API. The questions are a little bit easier and more practical than those companies. First, even though it has questions from Data Structures and Algorithms like String or Array, you can still manage to clear Java interviews if you are not an expert on them. Java Interviews are a little bit different than traditional programming interviews on tech giants and product-based companies like Google, Amazon, Microsoft, or Facebook.
