英文:
How does one get a child of a parent class from another child
问题
我有4个类：A，B是A的子类，D是A的子类，C是B的子类。
基本上：
public class A { }
public class B extends A { }
public class C extends B { }
public class D extends A { }
在Java中有没有可能从C类对象获取一个对象类型为D的对象？
英文:
I have 4 classes: A, B which is a child of A, D which is a child of A and C which is a child of B.
Basically:
public class A { }
public class B extends A { }
public class C extends B { }
public class D extends A { }
Is there any possible way to get an object type D from a C class object in java?
