Question

爲什麼這個通用的接口實現不兼容？

//The type Client<T> must implement the inherited abstract method IClient.compareTo(IClient) 
class Client<T> implements IClient { 

    //The method compareTo(IClient<T>) of type Client<T> must override or implement a supertype method 
    //The Eclipse quick fix creates exactly the same supertype method which is defined in the interface. 
    @Override 
    public int compareTo(IClient<T> o) { 
     return this.getClass().getName().compareTo(o.getClass().getName()); 
    } 
} 

interface IClient<T> extends Comparable<IClient<T>> { 

    @Override 
    int compareTo(IClient<T> o); 

} 

Answer 1

哦，我發現有一個名稱衝突： 類型的客戶端的方法的compareTo（IClient）具有相同的擦除爲的compareTo（IClient）型在iClient但不覆蓋它。

IClient是一種原始類型。參考通用類型IClient應參數化

class Client<T> implements IClient<T>將修復它。

Answer 2

class Client<T> implements IClient<T> {
