Access modifiers are a specific part of programming language syntax used to facilitate the encapsulation of components. [1] In C++, there are only three access modifiers. C# extends the number of them to six, [2] while Java has four access modifiers, but three keywords for this purpose. In Java, having no keyword before defaults to the package ...
Packages are a part of a class name and they are used to group and/or distinguish named entities from other ones. Another purpose of packages is to govern code access together with access modifiers. For example, java.io.InputStream is a fully qualified class name for the class InputStream which is located in the package java.io.
In computer science and computer programming, access level denotes the set of permissions or restrictions provided to a data type. Reducing access level is an effective method for limiting failure modes, reducing debugging time, and simplifying overall system complexity. It restricts variable modification to only the methods defined within the ...

The bridge pattern is often confused with the adapter pattern, and is often implemented using the object adapter pattern; e.g., in the Java code below. Variant: The implementation can be decoupled even more by deferring the presence of the implementation to the point where the abstraction is utilized.
There are many different types of software available to produce charts. A number of notable examples (with their own Wikipedia articles) are given below and organized according to the programming language or other context in which they are used.
Example of a Structured Chart. [1] A structure chart (SC) in software engineering and organizational theory is a chart which shows the smallest of a system to its lowest manageable levels. [2] They are used in structured programming to arrange program modules into a tree. Each module is represented by a box, which contains the module's name.
A Nassi–Shneiderman diagram (NSD) in computer programming is a graphical design representation for structured programming. [1] This type of diagram was developed in 1972 by Isaac Nassi and Ben Shneiderman who were both graduate students at Stony Brook University. [2] These diagrams are also called structograms, [3] as they show a program's ...
