Many languages allow generic copying by one or either strategy, defining either one copy operation or separate shallow copy and deep copy operations. [1] Note that even shallower is to use a reference to the existing object A, in which case there is no new object, only a new reference. The terminology of shallow copy and deep copy dates to ...
An example of such a language is Java prior to Java 9, which lacked the Java Platform Module System, a module system at the level of components introduced with Java 9. Java till Java 8 merely had a package system, but Java software components typically consist of multiple Java packages – and in any case, interface programming can provide ...
The Java Platform Module System [1] specifies a distribution format for collections of Java code and associated resources. It also specifies a repository for storing these collections, or modules , and identifies how they can be discovered, loaded and checked for integrity.
java.util.Collection class and interface hierarchy Java's java.util.Map class and interface hierarchy. The Java collections framework is a set of classes and interfaces that implement commonly reusable collection data structures. [1] Although referred to as a framework, it works in a manner of a library. The collections framework provides both ...
An interface in the Java programming language is an abstract type that is used to declare a behavior that classes must implement. They are similar to protocols.Interfaces are declared using the interface keyword, and may only contain method signature and constant declarations (variable declarations that are declared to be both static and final).
Modules describe their dependencies in a declaration placed in a file named module-info.java at the root of the module's source-file hierarchy. Since Java 9, the JDK is able to check the module dependencies both at compile time and runtime. The JDK itself is modularized for Java 9. [8] [9]

The term assembly (as in .NET languages like C#, F# or Visual Basic .NET) or package (as in Dart, Go or Java) is sometimes used instead of module.In other implementations, these are distinct concepts; in Python a package is a collection of modules, while in Java 9 the introduction of the new module concept (a collection of packages with enhanced access control) was implemented.
