Is there any efficient algorithm for traversing a Heap-Based Priority Queue?
I have implemented a Heap-Based Priority Queue in Java but my challenge now is implementing an efficient Iterator that has a definite (increasing or decreasing) order of traversal. Is there any algorithm that does this at constant auxiliary space and time complexity of O(n)? The O(nlogn) is quite trivial. Also, there is absolutely no subtlety in O(n) space algorithm. Please
How to create a list of class names and iterate throught the static methoc in it?
I have list of classes: List<Class<?>> = Array.asList(ClassA, ClassB, ClassC, ClassD); each of them has a static method staticMethod(byte[] bytes) How can I iterate through this list of classes and calling the staticMethod? Answer Represent your List like lambda expressions for your static methods. Full code: Output: EDIT: Example for methods with return value:
How to map Iterable to its DTO?
I have the following repository: PermissionRepository: In my service, I am trying to map Permission entity to PermissionDTO, but as findAll() method returns Iterable<T> (Iterable<T> findAll();), I cannot convert as shown below as I generally use for List<T>. It throws “Cannot resolve method ‘stream’ in ‘Iterable'” error for the .stream() method. So, how can I map this Permission entity to
Can I add html component every two elements of a list from Java model using Sighlty?
I need to iterate every two elements of a list from model Java using Slightly. So I can add html components every two elements. Can you help me, please? Answer According to the HTL specification: An additional itemList (respectively <variable>List in case a custom identifier/variable was defined using data-sly-list.) identifier is also available within the scope, with the following members:
Java Iterator – infinite loop
What am I doing wrong? Why does this iterator keep running? The feasibility function checks if the element is viable, if yes assign the element to the list. Then the solution checks if this is the ‘algo’ solution and returns the list, else check the next element in the list. Answer next should always be executed inside the loop. If
Java Iterator in C++
I am a Java user and I am getting into C++ and in Java it allows classes to reveal Iterable types so clients can traverse some instance’s collection of data. Is there any way to obtain this …
How to add an object during ListIterator (reversed) iteration properly?
I have been asked from my professor to add an object in the middle of an ArrayedList<Employee> using listiterator. I have tried doing in the following way first: But this produces a seemingly infinite number of iterations where li.nextIndex() gets stuck on 5. I have verified this with the debugger and this happens only after li.add(emp_M) is evaluated. I have
Iterator hasNext for the last record fetching
As per my understanding, i.hasNext() method checks whether the next entry exists or not and returns true or false. And the i.next() method above here, will display the current linkedList record and then increments/moves to the next record. If we are in the last record, i.hasNext() is false, how is it still executing the last iteration of i.next()? Answer I
