GOF Design Patterns.SOLID design principles.Abstract class and interface.Java basics e.Generics and Enum.Java IO and NIOCommon Networking protocols.Data structure and algorithm in Java.Regular expressions.JVM internals.Java Best Practices.JDBCDate, Time, and Calendar.XML Processing in Java.JUnit.

Programming.You guys are also lucky that nowadays there are some good books available to prepare for Java interviews, one of them which I particularly find useful and interesting to read is Java Programming Interview Exposed by Markham.Simatic Step 7 Keygen Download Pc .It will take you to some of the most important topics for Java and JEE interviews, worth reading even if you are not preparing for Java interview.Top 1.Java Interview Questions Answers.So now the time has come to introduce you to this MEGA list of 1.Java questions collected from various interviews of last 5 years.I am sure you have seen many of these questions personally on your interviews and many of you would have answered them correctly as well.Multithreading, Concurrency and Thread basics Questions.Can we make array volatile in Java This is one of the tricky Java multi threading questions you will see in senior Java developer Interview.Yes, you can make an array volatile in Java but only the reference which is pointing to an array, not the whole array.What I mean, if one thread changes the reference variable to points to another array, that will provide a volatile guarantee, but if multiple threads are changing individual array elements they wont be having happens before guarantee provided by the volatile modifier.Can volatile make a non atomic operation to atomic This another good question I love to ask on volatile, mostly as a follow up of the previous question.This question is also not easy to answer because volatile is not about atomicity, but there are cases where you can use a volatile variable to make the operation atomic.One example I have seen is having a long field in your class.If you know that a long field is accessed by more than one thread e.Why because reading to a long variable is not atomic in Java and done in two steps, If one thread is writing or updating long value, its possible for another thread to see half value fist 3.While readingwriting a volatile long or double 6.What are practical uses of volatile modifier One of the practical use of the volatile variable is to make reading double and long atomic.Both double and long are 6.Java.
