Using the Java language, recursive algorithms are used to compute the number of 1 in the binary representation of an integer n /*use the recursive Algorithme to calculate * The number of "1" in the binary expression * of the Integer N. *

Whether you care or not, Java Web applications use a thread pool more or less to process requests. The implementation details of the thread pool may be overlooked, but the use and tuning of the thread pool will need to be understood sooner or later.

Overview Bubble sort is a simple sort algorithm. It repeatedly visits the sequence to be sorted, compares two elements at a time, and swaps them if their order is wrong. The task of visiting the series is repeated until the sequence has been sorted.

definition: encapsulates a request into an object, allowing you to parameterize clients using different requests, queuing up requests, or logging request logs, to provide revocation and recovery capabilities for commands.Type: behavior class

Theoretically the object class is the parent class of all classes, that is, directly or indirectly inheriting the Java.lang.Object class. Because all classes inherit from the object class, the extends object keyword is omitted.The main methods in
