This article mainly explains "how to use Java recursive method". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn how to use Java recursive method.

1. Recursion

(1) Recursive introduction:

From a programming point of view, recursion refers to the phenomenon of invoking the method itself in the method definition, transforming a complex problem layer by layer into a smaller problem similar to the original problem to solve. The recursive strategy requires only a small number of programs to describe the repeated calculations needed in the problem-solving process.

(2) the basic use of recursion:

(3) points for attention of recursion:

Recursion must have an exit, otherwise memory overflow; although recursion has an exit, but the number of recursion should not be too much, otherwise memory overflow.

2. Recursive factorial

Case requirements: use recursion to find the factorial of 5, and output the results in the console.

Code implementation:

3. Recursively traverse the directory

Case requirements: given a path (E:\\ itcast), iterate through all the contents of that directory recursively, and output the absolute paths of all files to the console.

Code implementation:

Thank you for your reading, the above is the content of "how to use Java recursive method". After the study of this article, I believe you have a deeper understanding of how to use Java recursive method, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
