In Java (and Ada, C#, and others), namespaces/packages express semantic categories of code. For example, in C#, namespace System contains code provided by the system (the .NET Framework). How specific these categories are and how deep the hierarchies go differ from language to language.
A C# namespace provides the same level of code isolation as a Java package or a C++ namespace, with very similar rules and features to a package. Namespaces can be imported with the "using" syntax. Namespaces can be imported with the "using" syntax.
The C# System.Int64 type is exactly the same type as the long type; the only difference is that the former is the canonical .NET name, while the latter is a C# alias for it. Java does not offer methods directly on primitive types. Instead, methods that operate on primitive values are offered through companion primitive wrapper classes. A fixed ...
Runtime exception handling method in C# is inherited from Java and C++. The base class library has a class called System. Exception from which all other exception classes are derived. An Exception-object contains all the information about a specific exception and also the inner exceptions that were caused.
In some scenarios a namespace requires that the global elements that compose it are initialized and finalized by a function or method call. In many programming languages, namespaces are not directly intended to support an initialization process nor a finalization process, and are therefore not equivalent to modules. That limitation can be ...
But it can span over several namespaces. Also, one namespace can spread over several assemblies. In large designs, an assembly may consist of multiple files that are held together by a manifest (i.e. a table of contents). In C#, an assembly is the smallest deployment unit used, and is a component in .NET. In Java, it is a JAR file. [1]
[3] and C#. [4] In Java, ActionScript, [5] and other object-oriented languages the use of the dot is known as "dot syntax". [6] Other examples include: As an example of a relational database, in Microsoft SQL Server the fully qualified name of an object is the one that specifies all four parts: server_name.[database_name].[schema_name].object ...
For example, name resolution in assembly language usually involves only a single simple table lookup, while name resolution in C++ is extremely complicated as it involves: namespaces, which make it possible for an identifier to have different meanings depending on its associated namespace;
