Java Native Interface, Java's native method support, allows Java language programs to call out to programs written in another language (usually C or C++). There are two name-resolution concerns here, neither of which is implemented in a standardized manner: JVM to native name translation - this seems to be more stable, since Oracle makes its ...

Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly. In object-oriented languages, string functions are often implemented as properties and methods of string objects.
Prefixing with double underscores changes behaviour in classes with regard to name mangling. Prefixing and suffixing with double underscores - the so-called "dunder" ("double under") methods in Python - are reserved for "magic names" which fulfill special behaviour in Python objects. [40]
Multiple dispatch or multimethods is a feature of some programming languages in which a function or method can be dynamically dispatched based on the run-time (dynamic) type or, in the more general case, some other attribute of more than one of its arguments. [1]
In programming languages, name resolution can be performed either at compile time or at runtime. The former is called static name resolution, the latter is called dynamic name resolution. A somewhat common misconception is that dynamic typing implies dynamic name resolution. For example, Erlang is dynamically typed but has static name ...
A method has a return value, a name and usually some parameters initialized when it is called with some arguments. Similar to C++, methods returning nothing have return type declared as void. Unlike in C++, methods in Java are not allowed to have default argument values and methods are usually overloaded instead.
The single copy of each string is called its intern and is typically looked up by a method of the string class, for example String.intern() [2] in Java. All compile-time constant strings in Java are automatically interned using this method. [3] String interning is supported by some modern object-oriented programming languages, including Java ...
