问题描述
如何使用计算斐波那契数列的方法? -
解决方案
这个例子展示了使用方法计算斐波那契数列直到数字的方法。public class MainClass { public static long fibonacci(long number) { if ((number == 0) || (number == 1)) return number; else return fibonacci(number - 1) + fibonacci(number - 2); } public static void main(String[] args) { for (int counter = 0; counter <= 10; counter++){ System.out.printf("Fibonacci of %d is: %d\n", counter, fibonacci(counter)); } } }

结果
上面的代码示例将产生以下结果。Fibonacci of 0 is: 0 Fibonacci of 1 is: 1 Fibonacci of 2 is: 1 Fibonacci of 3 is: 2 Fibonacci of 4 is: 3 Fibonacci of 5 is: 5 Fibonacci of 6 is: 8 Fibonacci of 7 is: 13 Fibonacci of 8 is: 21 Fibonacci of 9 is: 34 Fibonacci of 10 is: 55
下面是斐波那契数列的另一个例子public class ExampleFibonacci { public static void main(String a[]) { int count = 15; int[] feb = new int[count]; feb[0] = 0; feb[1] = 1; for(int i = 2; i < count; i++) { feb[i] = feb[i-1] + feb[i-2]; } for(int i = 0; i < count; i++) { System.out.print(feb[i] + " "); } } }
上面的代码示例将产生以下结果。0 1 1 2 3 5 8 13 21 34 55 89 144 233 377
