菜鸟请教一个java的基础面试题。
------------------------------------------------------
public class D
{
public int a=10;
public int test() { return a; }
}
------------------------------------------------------
public class E extends D
{
public int a=20;
public int test() { return a; }
}
------------------------------------------------------
Now suppose
D d=new E();
So d.a = ? and d.test()=?
I understand d.test() is 20, due to inheritance finds the lowest level method and call.
But why d.a is 10?
