Simple definition and usage example of circular queue of Java data structure

This paper describes the simple definition and usage of circular queue of Java data structure. Share with you for your reference, as follows:

1、 Overview:

1. Principle:

The difference from the normal queue is that when adding data to the circular queue, if its effective data end = = maxsize - 1 (maximum space), the end pointer moves to the position of - 1

When deleting data, if head = = maxsize, the head pointer moves to the position of 0
