![]() A thread’s id is assigned the first time it invokes ThreadId.get() and remains unchanged on subsequent calls. It’s useful for both beginners having 2 to 3 years of experience as well as experienced Java programmers with 5 to 6 years of experience. ![]() The example below, from the ThreadLocal Javadoc, generates unique identifiers local to each thread. These are frequently asked Java interview questions. ThreadLocal instances are typically private static fields in classes that wish to associate state with a thread (e.g., a user ID or transaction ID). Each thread that accesses the get() or set() method of a ThreadLocal instance is accessing its own, independently initialized copy of the variable. If you are a new learner in the field of programming or want to upskill and take your career to the next level, CodeQuotient offers their flagship SuperCoders Program – a full-stack development internship.A single ThreadLocal instance can store different values for each thread independently. With these answers in your arsenal, you are well-equipped to handle some of the trickiest questions any Java interviewer can throw at you. No, you cannot access a non-static variable from the static context in Java, as it will give a compile-time error. Can you access a non-static variable in the static context? Answer: You can reuse CyclicBarrier even if the Barrier is broken, but you can not reuse CountDownLatch in Java. What is the difference between CyclicBarrier and CountDownLatch in Java? Answer: Yes, you can throw a superclass of RuntimeException in overridden method, but you can not do that if it’s a checked Exception. ![]() Every aspiring tester, especially one aiming to work with web-based. ![]() It is easy to use, simple, and provides support for writing test scripts in a wide variety of programming languages, including C, Groovy, Java, Perl, and Python. Coding Programs are like you have given some operations to perform. If a method throws NullPointerException in the superclass, can we override it with a method that throws RuntimeException? Answer: Written entirely in Java, Selenium is one of the most widely used automation testing tools. This coding question of Java Programming will help you to crack the coding interview rounds. On a Windows XP with the US locale, the above program prints 63, but if you run this program on Linux or Solaris, you will get different values.Ĩ. This question is particularly tricky because this program’s output depends on the operating system and locale. What will the following Java program print? Let us show you the ten most tricky Java programming questions you can expect in an interview, with solutions. Java Programming – Tricky Interview Questions However, clearing an interview for this job role isn’t all that easy, given that most interview panellists tend to throw tricky questions at the candidates to find the best talent for the job. As per Mercer, one of the global leaders in talent assessment, the role of a Java developer is one of the most in-demand roles in 2022, thanks to the ever-increasing adoption of Java in multiple domains, devices, and organisations. With over 9 million active Java developers globally, the demand for talent in this domain is at an all-time high. It is the number one development language for microservices and is the most-used language for DevOps, AI, VR, Big Data, Continuous Integration, Analytics, Mobile, Chatbots, and much more. With over 45 billion active virtual machines globally, Java is one of the most popular programming languages in the world. Every interview usually comes with tricky questions that trick candidates into thinking either too much or not at all. If you are preparing for a Java job interview, you must be familiar with these tricky programming questions.
