在Java中,如何使用方法来计算斐波纳契系列?
这个例子显示了如何使用方法来计算斐波纳契系列的数字。
package com.yiibai;
public class CalculatingFibonacciSeries {
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));
}
}
}
执行上面示例代码,得到以下结果 -
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
示例-2
以下是解决汉诺塔的另一个例子
package com.yiibai;
public class CalculatingFibonacciSeries2 {
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] + " ");
}
}
}
执行上面示例代码,得到以下结果 -
0 1 1 2 3 5 8 13 21 34 55 89 144 233 377
