When dealing with lists in Java, one of the most basic and commonly used methods to sort a list isCollections.sort(). This method sorts the elements of the list in ascending order according to their natural ordering. Here’s a simple example of how it works: List<String>fruits=Arrays.as...

此範例會針對名為 DinoCompare 的字串定義替代比較子,它會 IComparer<string> 在Visual Basic 中實作 Visual Basic 中的 (IComparer(Of String), IComparer<String^>) 泛型介面。 比較子的運作方式如下:首先,比較子會針對 null進行測試,並將 Null 參考視為小於非 Null。 其次,會比較字串長度,而且較長的字串...
