For example, for aListofEmployeeobjects, the natural order may be ordered by employee’s id. But in real-life applications, we may want to sort the list of employees by their first name, date of birth or simply any other such criteria. In such conditions, we need to useComparatorinterfac...
which makes the divisor to be zero. The method will only throw an Arithmetic exception to the programmer. So that the caller/ programmer will not come to know about the actual cause of the Exception. In this type of situation, we can use a...
Starting with Guava v21.0, we can useImmutableList.toImmutableList()static method which collects the elements into an Immutable List.

For the method annotated with@RepeatedTest,you may use @Tagto filter the tests with specific tags, @DisplayNameto add a customized name to the test method, @Orderto set priority for execution. These were few annotations that go well with @RepeatedTest, however, there are many more annotations...
Das eingebaute Modulqueuein Python bietet eine Priority-Queue-Implementierung. Das Modul erlaubt uns jedoch nicht, einen benutzerdefinierten Komparator für die Prioritätswarteschlange anzugeben. Dies kann ein Problem sein, wenn wir eine andere Reihenfolge als die Standardreihenfolge für die Pr...
The queue data structure uses the First In First Out (FIFO) principle. It is used to hold the object to be processed in order of their arrival; this is very similar to the line of people standing in a queue. As Java provides large support for data structure in the form of the Collect...
3. Visiting in order of node number This also happens a lot because many people use std::pair of each (node,distance)(node,distance) in priority_queue. Because the comparator of std::pair compares first first, by default the node with larger number will be popped first. If one used gre...
Since Queue is an interface, you cannot use it directly, either you need to use its implementation classes. JDK provides two implementations of the Queue interface, a PriorityQueue and LinkedList. A PriorityQueue allows you to consume elements based upon their priority, very useful to implement a...
