题目内容 (请给出正确答案)

给定以下代码,以下哪句是正确的? public class Test { String s; static class Inner { void testMethod() { s = "Hello world."; } } public static void main(String[] argv) { Inner i = new Inner(); i.testMethod(); System.out.println(s); } }

A.编译通过,但是运行时刻出错,因为s没有被初始化

B.无法编译,因为Test类里的String s不是static的

C.编译通过,打印出Hello world.

D.无法编译,因为Inner不能像这样在main中使用


参考答案和解析
D
