reference is a manipulation of the object, it must be initialized at the same time it is created (referencing a valid object, NOT NULL), the initialization is no longer immutable, the reference has the efficiency of the pointer, and the convenience and intuition of variable use, At the language level, as with the use of objects, references at the binary level are generally implemented by pointers, but the compiler helps us to complete the conversion. References are

DataGrid [Overview] Web development has undergone a lengthy process since it has scripted web programming technologies such as ASP. Through the use of Microsoft's ASP.net technology, the traditional ASP in a large number of tedious, repetitive programming work has become a history.

Fixed-capacity linkedhashmap based on the least recently used algorithm. Can be used as a simple cache. The use method is consistent with Linkedhashmap. Using Linkedhashmap to implement a simple cache, you must implement the Removeeldestentry method, see the JDK documentation. In addition, a reentrant mutex lock is added.

"5..1" means 5 to 1.When we are programming, using foreach may be a similar usage: Copy Code code as follows: foreach ($i in 1..5) { Write-host $i; } Double colon (::), static member operator.

Regular Expressions (Regular Expression, often abbreviated as regex, RegExp, or re) in code are a concept of computer science. A regular expression uses a single string to describe and match a series of strings that conform to a certain syntactic rule. In many text editors, regular expressions are often used to retrieve and replace text that conforms to a pattern. Many programming languages support the use of regular expressions for string manipulatio

At the SAP User Conference in Orlando recently, SAP released an impressive set of applications ' Fiori ', based on SAP's new HTML5 framework (i.e. SAPUI5). SAPUI5 (based on Html/css/javascript, on top of jquery, etc.) has been around for more than a year, but last week the Fiori application released by SAP has shown that SAP is very serious about SAPUI5 as a tool set for future UI development. DJ Adams a year ago in his blog has foreseen the transfer of SAPUI5 SAPUI5, our HTML5 Control Library,
