Recursion in CLIPS
Our example demonstrates recursive functions in Java. Here’s a classic example:
public class Recursion {
// This `fact` method calls itself until it reaches the
// base case of `fact(0)`.
public static int fact(int n) {
if (n == 0) {
return 1;
}
return n * fact(n - 1);
}
public static void main(String[] args) {
System.out.println(fact(7));
// In Java, we can achieve similar functionality to Go's recursive closures
// using lambda expressions and interfaces.
IntUnaryOperator fib = new IntUnaryOperator() {
@Override
public int applyAsInt(int n) {
if (n < 2) {
return n;
}
return applyAsInt(n - 1) + applyAsInt(n - 2);
}
};
System.out.println(fib.applyAsInt(7));
}
}This fact method calls itself until it reaches the base case of fact(0).
In Java, we don’t have closures in the same way as Go, but we can achieve similar functionality using lambda expressions and interfaces. Here, we’ve used the IntUnaryOperator interface to create a recursive function for calculating Fibonacci numbers.
To run the program:
$ javac Recursion.java
$ java Recursion

13In this example, we’ve demonstrated both a simple recursive method (fact) and a more complex recursive operation using a functional interface (fib). The fact method calculates the factorial of a number, while the fib operation calculates the Fibonacci number at a given position.
