無法得到這個編譯，我做錯了什麼？

Question

好吧，我可以看到第33行的「setUniqueType」和第50行的「ItemDetails」是需要糾正的，但我無法弄清楚它有什麼問題以及如何解決它。請幫助，所以我可以在我的程序移動...

編譯錯誤：

1. 你ItemDetails類沒有setUniqueType方法。你應該添加一個。
2. 您在48處使用的構造函數是「String，double，double，double，String」，但您的構造函數實際上只是「String double double double」或者刪除Type或在您的Item的末尾添加一個String參數構造函數，或使用這五個參數創建ItemDEtails構造函數。
3. Your ItemDetails沒有與該參數匹配的構造函數。如果你想鏈的構造函數，聲明它ItemDetails

鏈的構造：

public ItemDetails(String productName, double productNumber, double unitsInStock, double unitPrice 
    super(productName,productNumber,unitsInStock,unitPrice); 
} 

Answer 2

關於ItemDetails：它看起來像你的ItemDetails構造，從項目繼承，只需要4指定參數和你」重新傳遞它5.
