下面的代码中有什么错误吗？_______
using System;
class A
{
public virtual void F(){
Console.WriteLine("A.F");
}
}
abstract class B:A
{
public abstract override void F();

{
public B()
{
Console.WriteLine('B');

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？
public class Something {
public int addOne(final int x) {
return ++x;
}
}
这个比较明显。
A.import jav
B.awt.
C.package mypackage
D.class OtherClass{ }
E.public class MyClass{ }
在下面的例子里
using System;
class A
{
public A()
{
PrintFields();
}
public virtual void PrintFields(){}
}
class BA
{
int x=1;
int y;
public B()
{
y=-1;
}
public override void PrintFields()
{
Console.WriteLine(x={0},y={1},x,y);
}
当使用new B()创建B的实例时，产生什么输出？
public class Something {
void doSomething () {
private String s = "";
int l = s.length();
}
}
有错吗？
