以下代码的运行结果为：public class ex2 { public static void main(String[] args) { int total = 0; for(int i = 0,j = 10;total > 30;++i,--j){ System.out.println("I = " + i + " ;j = " + j); total += (i+j); } System.out.println("Total: " + total); }}
选项：

A:产生运行错误;
B:产生编译错误;
C:输出“Total: 0”;
D: 输出如下结果： i = 0 ;j = 10 i = 1 ;j = 9 i = 2 ;j = 8 Total: 30
