Java、对数列求和

package Recursive;
 
public class Exercise18_04 {
    public static void main(String[] args) {
        for (int i = 1; i <= 10; i++)   //计算m(i)，i = 1,2,...10
            System.out.println("m(" + i + ") is " + m(i));
    }
 
    /** 返回数列和 */
    public static double m(int i) {
        return (i == 1) ? 1 : ((1.0 / i) + m(i - 1));
    }
}
