我有 Hibernate 方法，它返回一個 BigDecimal.我有另一個 API 方法，我需要將該數字傳遞給它，但它接受 Integer 作為參數.我無法更改這兩種方法的返回類型或變量類型.
I have Hibernate method which returns me a BigDecimal.
I have another API method to which I need to pass that number but it accepts Integer as parameter. I cannot change return types or variable types of both methods.
現在如何將 BigDecimal 轉換為 Integer 并將其傳遞給第二個方法?
Now how to convert the BigDecimal into Integer and pass it to second method?
You would call myBigDecimal.intValueExact() (or just intValue()) and it will even throw an exception if you would lose information. That returns an int but autoboxing takes care of that.
