What's the difference between java loops and recursion?
This article mainly introduces "what is the difference between java loop and recursion". In daily operation, I believe that many people have doubts about the difference between java loop and recursion. Xiaobian consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the question of "what is the difference between java loop and recursion". Next, please follow the editor to study!
Description
1, the general recursive call can handle the algorithm, but also through the loop to solve the need for additional inefficient processing.
2. After optimization, the current compiler will have a very good efficiency optimization for the method processing that is called many times, and the efficiency may not be lower than that of the loop.
Cycle
Advantages: simple structure
Disadvantages: it doesn't solve all the problems. Some problems are suitable for using recursion instead of loops, and if it is not difficult to use loops, it is best to use loops.
Recursion
Advantages: the code is simple, clear, and easy to verify correctness
Disadvantages: its operation requires a large number of method calls. If the number of call layers is deep, additional stack processing is needed, such as parameter passing requires stack pressing, which will affect the execution efficiency to a certain extent. However, for some problems, if you do not use recursion, it will be extremely ugly code.
What is Java? Java is an object-oriented programming language that can write desktop applications, Web applications, distributed systems, and embedded system applications.
At this point, the study of "what is the difference between java loops and recursion" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
