The implementation principle of Linkedblockingqueue is analyzed in detail in the previous section. There are usually two ways to implement an extensible queue: one is to use a linked list like linkedblockingqueue, which means that each element has a

In programming, we almost always need to organize a group of the same kind of objects, such as a bunch of students or a group of workers, because of their number is not determined, we need a thing to help manage, this is used to manage the things

Array overviewThe C # array is indexed from zero, that is, the array index is zero-based. Arrays in C # work similar to how they work in most other popular languages. But there are some differences that should be brought to the attention. When
