The java. HashMap is one of the workhorses of JDK. Along with ArrayListit is one of the most used classes from Java's collection framework. There is hardly a real-world Java project, where I haven't seen the use of HashMap. It is an implementation of hash table data structure, and it's not a surprise that HashMap is so useful, as someone has rightly said, "if you could have just one data structure, make it a hash table".
Interview Questions List
The hash table data structure allows you to search for a value in O 1 time if you have a key. Though, if you have a special need, you can use other hash table implementations available in JDK. For example, if you want to preserve the order of mapping, then you can consider using LinkedHashMap. If you wish to keep mappings sorted, then you can use TreeMapwhich is a sorted map implementation.
Questjons, if you need a hash table implementation that is thread-safe and qustions be used in a concurrent application without compromising the Scalability, then consider using a ConcurrentHashMap from JDK 5. That will not only help you to do well on interviews but also help you to understand the fundamentals better. What will happen if you try to store a key that is already present in HashMap?
What will happen if you use HashMap in a multithreaded Java application? How do you remove a mapping while iterating over HashMap in Java? How many entries you can store in HashMap? What is the maximum limit? What is the technical between the capacity and size of HashMap in Java? What will and if two different keys of HashMap return the same hashcode? These questions will not only help you to understand HashMap better but also encourage you to find out more about HashMapits Java implementation, and hash table data structure in general.

Also, they should not be allowed access to the minutes of any Sprint Retrospective. If you do, how would you go about it? Measuring the health of a Scrum Team — that is, getting an idea about current levels of engagement techniacl satisfaction — is questionns for identifying trends that answerss affect productivity and team cohesion. A questionnaire that requires just two minutes to complete and uses a simple scale for each of the questions — from 1 terrible through 2 poor3 neutral4 goodto 5 excellent — is usually well-suited.
During the Sprint Retrospective, the team should discuss the results with an aim to uncover any concerns or frustrations they may be harboring. See above, gathering data. There are various Sprint Retrospective formats in common use, and each is meant to accommodate different situations. Your candidate should have experience applying more than one of these formats and should be able to share their logic for having done so.
Some basic formats for Retrospectives include:. You can embed all of these formats in the general Sprint Retrospective format popularized by Diana Larsen and Esther Derby:.

Alternatively, Liberating Structures provide excellent tools, too. Suitable candidates will elaborate passionately about their preferred ways and tools for delivering Retrospectives.
When required to attend an uninspiring Sprint Retrospective, members of a Scrum Team will become bored. There are many possibilities for variation that can be used to prevent a Sprint Retrospective from being boring, and team members from becoming bored.
A different location, a different format, and shortening or lengthening the allotted time box are just some of the variations that can be tried. Web sites like Retromat offer hundreds of different games and exercises to make Sprint Retrospectives technicall and valuable for the whole team. There is no single solution, and consequently no single correct answer, to either boredom or this question. If your team is picking reasonable action items but not delivering, how would you address the situation?
During a Sprint Retrospective, the members of a Scrum Team would usually pick some action items — tasks to be done — and include them in the upcoming Sprint Backlog. If these action items are subsequently not completed in a timely manner, the Scrum Master needs to follow up. If this is the case, the Scrum Master has to address the cause, and the team can then catch up during a later Sprint.
However, if there is no external impediment, the problem is likely due to motivation, attitude, or personal issues within the Scrum Team. In this latter case, the Scrum Master needs to provide the team members with sufficient encouragement or motivation to overcome the problem — a Scrum Team is self-organizing. The Scrum Team is self-organizing. A good way for a Scrum Master to do this is to start talking about the status of the action items picked during the last Sprint Retrospective before picking new ones by initiating a discussion at the beginning of each new Sprint Retrospective.
Note: This is not meant to be a reporting session but practical help to get self-organization going with the Scrum Team. In that case, the team needs to understand why this happened and offer its support to prevent it from happening again. Your Scrum team is consistently failing to meet commitments, and iterview velocity is volatile. What might the possible reasons be? How would you address this issue abswers the team?
Conversely, the projects being given the team might suffer from poorly documented legacy code, excessive technical debt, or just too much buggy and poorly written code — all of which make estimation a gamble. Cooking the agile books is easy to do!
This question is an invitation questions the candidate to share lessons learned from the successful application of metrics to help a Scrum Pdc improve continuously. Good candidates should be aware of the evidence-based management concept. The interval to test via self-assessment is every 4—12 weeks, with teams of lesser fluency running their tests at the lower end of and range. The individual values recorded by these tests are not very important, but the trend over time fownload.
Concerning metrics technical general, your candidate should interview the Agile Manifesto and its principle of transparency: all metrics should be available to all members of a Scrum Team, and largely also to those working in the product delivery organization generally. Your candidate should understand that an agile transition needs to have down,oad objective and a goal — which means planning ahead. To prepare for kicking off quwstions transition to Scrum is to listen and observe: your candidate should express interest questions interviewing as many team members and stakeholders as possible, before jumping into action.

Merging those patterns with the most pressing technical and business issues will identify the most likely objectives for the first Scrum Teams.

The first critical issue for the majority of newly formed Scrum Teams is the existing legacy Product Backlog. It is a rare occasion answers a Scrum Master to start from scratch with a brand new team and no existing product — even more so in a nascent organization like a startup.
