Here are some frequently asked questions form Java IO. Philosophy deals with questions that arise when people reflect on their lives and their world. Here is the sample code which uses right way o remove elements from ArrayList while looping over and avoids ConcurrentModificationException.
The resistance is influenced by the resistivity constant of the object determined by the material it is made out of. Cloneable is marker interface and doesn't contain any method clone method is defined in the object class.
For a uniform electric field, the field lines are straight, parallel and equally spaced. The magnitude of the field at a point corresponds to the density of the field lines around that point. The question form was popular for guiding confessors, and it appeared in several different forms: Learning[ edit ] Questions are used from the most elementary stage of learning to original research.
The interviewer has been asking this question since the day Serialization was introduced in Java, but yet only a few good candidate can answer this question with some confidence and practical knowledge. This may range from a simple yes or no in the case of yes—no questions to a more complex or detailed answer.
Here is the standard idiom of using wait and notify method in Java: Runtime class to get the free memory, total memory and maximum heap memory in Java.
In the case of factory pattern, the class also needs to know about factory to acquire dependency. JDK stands for Java development kit and provides tools to develop Java program e. Date and Time API, finally you have a solid and easy to use date and time library right into JDK Extension methods, now you can have static and default method into your interface Repeated annotation, allows you apply the same annotation multiple times on a type What is the difference between Maven and ANT in Java.
Quis, quid, quando, ubi, cur, quem ad modum, quibus adminiculis. Look there are many best practices and I give extra points to the developer which bring something new, something even I don't know. Assess the Cold War of the 20th century in an historical context: It's rather simple to answer and that's why many interviewers prefers to ask this question on the telephonic round.
Remember that the direction of the conventional current is the opposite to that of the flow of electrons. How was the assassination of Abraham Lincoln plotted and executed. Most common example is an Object which contain the reference of java.
Comparable can be always one, but we can have multiple comparators to define customized order for objects. Electric field Electric fields can be graphically represented as electric field lines. One of the practical use of the volatile variable is to make reading double and long atomic. The composition is stronger association than Aggregation.
The size of an int variable is constant in Java, it's always bit irrespective of platform. Which means, if you write to volatile field then it's guaranteed that any thread accessing that variable will see the value you wrote and anything you did before doing that right into the thread is guaranteed to have happened and any updated data values will also be visible to all threads, because the memory barrier flushed all other writes to the cache.
Yes, two unequal objects can have same hashcode that's why collision happen in a hashmap. It also supports abstraction because a client can use interface method to leverage multiple implementations e. Both double and long are bit wide and they are read in two parts, first bit first time and next bit second time, which is non-atomic but volatile double and long read is atomic in Java.
Participants were randomly assigned to either a control group who were simply told to learn as many of the words as possible in preparation for a final test or to a retrieval practice instructions group who were given 1 information about the superiority of retrieval over restudying; 2 a graph supporting this information; and 3 the advice that the best way of learning for the recall test was to ensure that each translation had been recalled at least three times before dropping it from study.
If your client is using some interface but you have something else, you can write an Adapter to bridge them together. These are the ones which are a sub class of Exception but doesn't descend from RuntimeException.
Create space on your desk for three piles of cards: Some "classic" questions of philosophy are speculative and theoretical and concern the nature of knowledge, reality and human existence: It is given by the ratio between the electric potential difference V and the current induced I.
How did Julius Caesar affect Rome. Serializable interface is used to make Java classes serializable so that they can be transferred over network or their state can be saved on disk, but it leverages default serialization built-in JVM, which is expensive, fragile and not secure.
