下列注释的哪两个代码(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 }}
