# What is recursions in java

The function called itself is called recursion. For example, a factorial program

```
int factorial(int number) { if(number == 0) { return 1; } factorial_i(number, 1);}int factorial_i(int currentNumber, int sum) { if(currentNumber == 1) { return sum; } else { return factorial_i(currentNumber - 1, sum*currentNumber); }}
```
