This article introduces you what the recursive algorithm in java algorithm is, the content is very detailed, interested friends can refer to, hope to be helpful to you.

In fact, in the program, we can understand that we can call ourselves. Using recursion to do related calculations is a regular logic. The next step of calculation needs to use the results of the previous step or several steps. For example, when we are doing continuous addition, multiplication and factorial, traversing folders, and so on, two conditions must be met for recursive return:

1. Every time you call yourself, you must be close to the result.

two。 There must be a termination process in a limited number of calculations.

If you do not follow the above conditions, it will often make recursion into an endless loop, so that there is only recursion without recurrence.

Let's use recursion to print out the 99 multiplication table in Java.
