Since we encapsulate database access, if we query a series of results returned by the database, for example, we get the username of all users from the database, and then display it on the JSP page. There is a general question here: Is this JavaBean

I. Block-level elements and row-level elements   To understand the differences between display: inline, block, and inline-block, you must first understand the features of block-level and line-level elements in HTML. In-line elements are also called

Display: block indicates that an element is displayed as a block-level element. The block element has the following features:Always starts on a new line;Height, row height, and top and bottom margins can be controlled;The default width is 100% of

Display: inline; inline elements are displayed in the same line.Display: block; block-level elements. In short, there is a line break that will be switched to the second line.Display: inline-block, which is a block-level element in the same row.The

The iterator provides a way to access an aggregate object sequentially without exposing the internal details of the object. Net foreach is a typical iterator mode. Figure: Code: VcD4KPHA + logs/nytvstwvcd4kpha + PHByZSBjbGFzcz0 = "brush: java;"

I. INTRODUCTIONToday, learning about the iterator pattern in design mode, the iterator pattern is a very, very common design pattern, so useful, c#,java it as a built-in implementation, C + + also provides STL iterators, which we use every day, but

iterator pattern definition: Provides a way to access a set of aggregated elements in a sequential manner without exposing the object's internal structure. Description: First of all, the object using an iterator must be a set of aggregated objects,

Iterator Pattern Iterator ModeScenario ConjectureIf you write code frequently, you will encounter traversing an array. Use the for loop to obtain the array subscript and perform further operations. For example, the following code: Int [] array = new

The so-called Iterator mode provides a unified access mode for different containers. This article uses java containers as an example to simulate the principle of Iterator. For more information, see 1. First define a container Collection
