Java生成斐波那契数列（0,1,1,2,3,5,8,13,21，……）:while循环，for循环分别实现

在Java中，我们可以使用while循环和for循环来生成斐波那契数列。下面我会分别给出两个实现方法。

**While循环实现：**

public class Fibonacci {
    public static void main(String[] args) {
        int n = 10; // 指定生成前n项
        int t1 = 0, t2 = 1;
        System.out.print("Fibonacci Series up to " + n + ": ");
        
        while (n > 0) {
            System.out.print(t1 + ", ");
            int sum = t1 + t2;
            t1 = t2;
            t2 = sum;
            n--;
        }
    }
}

**For循环实现：**

public class Fibonacci {
    public static void main(String[] args) {
        int n = 10;
        int[] fibSeries = new int[n];
        fibSeries[0] = 0;
        fibSeries[1] = 1;

        for (int i = 2; i < n; i++) {
            fibSeries[i] = fibSeries[i - 1] + fibSeries[i - 2];
        }

        System.out.println("Fibonacci Series up to " + n + ": ");
        for (int num : fibSeries) {
            System.out.print(num + ", ");
        }
    }
}

这两个程序都会打印出指定数量（这里是10项）的斐波那契数列。
