Top Tricky Java interview questions and Answers What is a tricky question? Well, tricky Java interview questions are those questions that have some surprise element on them. If you try to answer a tricky question with common sense, you will most likely fail because they require some specific knowledge. Most of the tricky Java questions come from confusing concepts like method overloading and overriding, Multi-threading which is really tricky to master character encoding, checked vs unchecked exceptions, and subtle Java programming details like Integer overflow. The most important thing to answer a tricky Java question is the attitude and analytical thinking, which helps even if you don't know the answer. Anyway in this Java article, we will see Java questions that are really tricky and requires more than average knowledge of Java programming language to answer them correctly. As per my experience, there is always one or two tricky or tough Java interview questionon any core Java or Java EE interviews, so it's good to prepare tricky questions from Java in advance. If I take an interview, I purposefully put this kind of question to gauge the depth of the candidate's understanding of Java. Another advantage of asking such a question is the surprising element, which is a key factor to put the candidate under some pressure during interviews. Since these questions are less common, there is a good chance that many Java developer doesn't know about it. You won't find these questions even on popular Java interview courses like the Java Interview Guide: 200 Interview Questions and Answers, which is nevertheless an excellent guide for Java interviews. ToP Tricky Java interview question - AnsweredHere is my list of ToP tricky Java interview questions, Though I have prepared and shared a lot of difficult core Java interview question and answers, But I have chosen them as the Top tricky questions because you can not guess answers to these tricky Java questions easily, you need some subtle details of Java programming language to answer these questions. Question: What does the following Java program print?Answer: This question is tricky because unlike the Integer, where''MIN_VALUEis negative, both theMAX_VALUEandMIN_VALUEof theDoubleclass are positive numbers. TheDouble.MIN_VALUE is 2^(-1074), a double constant whose magnitude is the least among all double values. So unlike the obvious answer,this program will print 0.0because ofDouble.MIN_VALUEis greater than 0. I have asked this question to a Java developer having experience of up to 3 to 5 years and surprisingly almost 70% of candidates got it wrong. If you are not familiar with essential Java data types and wrapper classes like Double and Float then I highly recommend you to join a comprehensive Java course like The Complete Java Masterclasson Udemy to learn them, they are very very important not just for interviews but also for day to day Java work.
