Implementing bounded generic with java

Question

I have an interface

public interface TransferObjectUtil<B extends BusinessObject,T> {

    public T to(B domain);

    public B from(T transferObject);
}

I am implementing the class for this as

public class ReflectionBasedTransferObjectUtil<B extends BusinessObject, T> implements
    **TransferObjectUtil<B extends BusinessObject, T>** {

For the portion within the ** in the above line the compiler complains that for B extends BusinessObject is not allowed. Why would it be so ?

I am just starting with generics, so pardon me for my novice question.

您使用仿制药的位置有点错误/过于急于尝试，请尝试这样

public class ReflectionBasedTransferObjectUtil<B extends BusinessObject, T> implements TransferObjectUtil<B, T> {
