These simplified accessors still retain the advantage of encapsulation over simple public instance variables, but it is common that, as system designs progress, the software is maintained and requirements change, the demands on the data become more sophisticated. Many automatic mutators and accessors eventually get replaced by separate blocks ...
Sometimes these accessor methods are called getX and setX (where X is the field's name), which are also known as mutator methods. Usually the accessor methods have public visibility while the field being encapsulated is given private visibility - this allows a programmer to restrict what actions another user of the code can perform. [1]
C++ uses the three modifiers called public, protected, and private. [3] C# has the modifiers public, protected,internal, private, protected internal, private protected, and file. [4] Java has public, package, protected, and private; package is the default, used if no other access modifier keyword is specified. The meaning of these modifiers may ...
If the variable's name and owner were declared as public, the accessor and mutator methods would not be needed. In Java 14, record classes were added to fight with this issue. [4] [5] [6] To reduce the amount of boilerplate, many frameworks have been developed, e.g. Lombok for Java. [7]
By declaring internal members public, or by providing free access to data via public mutator methods (setter). By providing non-public access. For example, see: Java access modifiers and accessibility levels in C# [1] In C++, via some of the above means, and by declaring friend classes or functions.

The set of basic C data types is similar to Java's. Minimally, there are four types, char, int, float, and double, but the qualifiers short, long, signed, and unsigned mean that C contains numerous target-dependent integer and floating-point primitive types. [15]
Language Integrated Query (LINQ, pronounced "link") is a Microsoft.NET Framework component that adds native data querying capabilities to .NET languages, originally released as a major part of .NET Framework 3.5 in 2007.
