By default, methods in C++ are not virtual (i.e., opt-in virtual). In Java, methods are virtual by default, but can be made non-virtual by using the final keyword (i.e., opt-out virtual). C++ enumerations are primitive types and support implicit conversion to integer types (but not from integer types).

Collection implementations in pre-JDK 1.2 versions of the Java platform included few data structure classes, but did not contain a collections framework. [4] The standard methods for grouping Java objects were via the array, the Vector, and the Hashtable classes, which unfortunately were not easy to extend, and did not implement a standard member interface.
Implemented as a retrofit for the java.util library having extra features, like data structures like sets and linked sets, and has several algorithms to manipulate elements of a collection, like finding the largest element based on some Comparator<T> object, finding the smallest element, finding sublists within a list, reverse the contents of a ...
In languages with single dispatch, classes typically also include method definitions. In languages with multiple dispatch, methods are defined by generic functions. There are exceptions where single dispatch methods are generic functions (e.g. Bigloo's object system).
For example, class UnicodeConversionMixin might provide a method unicode_to_ascii() when included in class FileReader and class WebPageScraper, which do not share a common parent. Abstract classes cannot be instantiated into objects; they exist only for inheritance into other "concrete" classes that can be instantiated.

In object-oriented languages, string functions are often implemented as properties and methods of string objects. In functional and list-based languages a string is represented as a list (of character codes), therefore all list-manipulation procedures could be considered string functions.
