阅读下面代码 public class Test { public static void main(String[]args) { System.out.println(2>0?10:8); } } 其运行的结果是A.2B.0C.10D.8
interface A{int x = 0;}class B{int x =1;}class C extends B implements A {public void pX(){System.out.println(x);}public static void main(String[] args) {new C().pX();}}
阅读下面的程序public class Test {public static void main(String[] args) {for(int x = 0 ; x A.跳出循环,无输出B.0121C.01D.0123
