Java学习——方法中传递参数分简单类型与复杂类型（引用类型）编程计算100＋98＋96＋。。。＋4＋2+1的值，用递归方法实现

package hello;

public class digui {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        System.out.println(1+sum(2));
    }
    public static int sum(int x)
    {
        if (x>100) {
            return 0;
        }
        return x+sum(x+2);
    }

}
