当你编译运行下列程序代码,会得到什么结果?private class Base{ Base(){ int i = 100; System.out.println(i); } }public class Pri extends Base{ staticint i = 200;public static void main(String argv[]){ Pri p = new Pri(); System.out.println(i); } }A.这段代码不能通过编译B.输出200C.输出100和200D.输出100

以下程序调试结果为:class Base{Base(){int i = 100;System.out.print (i);}}public class Pri extends Base{static int i = 200;public static void main(String argv[]){Pri p = new Pri();System.out.print(i);}} A.编译错误B.200C.100200D.100
