I have shared many posts about Java Interview Questions but in this article, I will share Java Interview questions and answers especially for junior Java developers. This includes college graduates, who are looking for the job, Java programmers who have 1 to 2 years of experience in Java and junior developers who have 2 to 4 years of experience in Java, C++ etc. At this level, Java questions are usually not very tough. If you have good knowledge of key programming areas e.g. data structure and algorithms, and a good understanding of Java programming language and JDK API, then you are in good shape. Interviewer often looks for candidates who are willing to learn, good at learning in quick time and knows basic stuff e.g. sorting list, searching through the array, starting stopping a thread and can read existing code. In this article, you will find questions from the areas targeted by Interview for freshers and Java developers with 1 to 4 years of experience e.g. coding, array, OOP, main method, Collections, ArrayList, Enums, Threads, design patterns, JDBC, SQL, Linux and other basic concepts.
