Question about recursion and threads

Recursion is when you have a method, and inside that method you call itself. Here's an example of how to get a specific index of the fibonacci sequence:
public int fib(int n) {
/* 0th and 1st indexes are 1 */
if (n == 0 || n == 1) {
return 1;
} else {
/* an index of the fibonacci sequence is the sum of the two previous terms */
return fib(n - 1) + fib(n - 2);
}
}

:confused:

Thanks, but how do I pause each iteration of the recursion loop using a thread?

Here's a simple program that prints 0 to 100 and pauses after each number:

public class Test
{
public static void main(String[] args) throws Exception
{
for(int x = 0; x < 100; x++)
{
System.out.println(x);
Thread.sleep(1000);
}
}
}

Thread.sleep(long millis) is what makes it pause, move this where you want your code to pause and it should work. Hope this helps.

Note that Thread.sleep() throws an InterruptedException.
