下列程序中注释的哪俩个代码（A，B，C，D）是错误的（无法通过编译）？
class Father{
private int money = 12;
float height;
int seeMoney(){
return money; //A
}
}
class Son extends Father{
int height;
int lookMoney(){
int m=seeMoney(); //B
return m;
}
}
class E{
public static void main (String args[]){
Son erzi = new Son();
erzi.money = 300; //C
erzi.height = 1.78F; //D
}
}
}
