下列程序的输出结果是 interface Inter{ public final static int A=100; } class My implements Inter{ public static void main (String args[ ]) {System.out.println(A) ; }A.100B.0C.AD.程序有错误
下列程序段中,正确的是______。 ①class MvClass { int var = 100; static int getVar() { return var; } } ②public class MyClass { final int date; void MyClass (int d) { date = d; } } ③public class MyMain { public static void main(String args[]) { System.out.println(Myclass1.date); } } class MyClass1 { int data = 10; } ④class IamAbstract { final int f; double d; abstrct void method(); }A.②④B.①③C.②D.以上都不对
public class Something {public static void main(String[] args) {Other o = new Other();new Something().addOne(o);}public void addOne(final Other o) {o.i++;}}class Other {public int i;}和上面的很相似,都是关于final 的问题,这有错吗?
下面程序执行的结果是【 】 include using namespace std; class A{ public: static in 下面程序执行的结果是【 】include<iostream>using namespace std;class A{public:static int x;A(inty){cout<<x+y;}};int A::x=2;void main(){A a(5);}
