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 ...
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.
Access levels modifiers are commonly used in Java [1] as well as C#, which further provides the internal level. [2] In C++, the only difference between a struct and a class is the default access level, which is private for classes and public for structs. [3]

Examples include the final keyword in Java and C++11 onwards or the sealed keyword in C#. Such modifiers are added to the class declaration before the class keyword and the class identifier declaration. Such non-subclassable classes restrict reusability, particularly when developers only have access to precompiled binaries and not source code.
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.
JFreeChart is an open-source framework for the programming language Java, which allows the creation of a wide variety of both interactive and non-interactive charts. JFreeChart, developed by David Gilbert , is available under the terms of the LGPL license.
From Java 8 onwards, the default keyword can be used to allow an interface to provide an implementation of a method. do The do keyword is used in conjunction with while to create a do-while loop , which executes a block of statements associated with the loop and then tests a boolean expression associated with the while .
