下面代码标注中哪个代码是错误的()classOutClass{intm=1;staticfloatx;//AclassInnerClass{intm=12;//Bstaticfloatn=20.89f;//CInnerClass(){}voidf(){m=100;}}voidcry(){InnerClasstom=newInnerClass();//D}}
由于内部类的实例化是由外部类实例化之后加载的,如果外部类还没有实例化,这时候调用内部类的静态成员,此时内部类还没有被加载,却要开始创建静态成员,这是矛盾的,所以java中不能存在内部有静态成员的非静态类。

以下程序段的输出结果是:inta=1,b;for(b=1;b<=10;b++){if(a>=8)break;if(a%2==1){a+=5;continue;}a-=3;}printf("%d\n",b);
第一轮:b=1,1<10,a=1,a>=8不成立,继续判断1%2=1成立,执行a=1+5=6,continue提前结束当前循环,直接进入下一次循环;第二轮:b=2,2<10,a=6,a>=8不成立,继续判断6%2=1...
以下程序输出结果是()。#include<stdio.h>structabc{inta,b,c;};main(){structabcs[2]={{1,2,3},{4,5,6}};intt;t=s[0].a+s[1].b;printf("%d\n",t);}
s[0].a=1,s[1].b=5
