The object that the variable points to is not influenced by that final variable though. In the above example, the origin's x and y coordinates can be freely modified. To prevent this undesirable situation, a common requirement is that all fields of an immutable object must be final, and that the types of these fields must be immutable themselves.
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.

While classic Rexx follows the "Everything is a String" philosophy and has string as its only data type, ooRexx considers everything as objects, including non-string objects such as arrays, streams and many more. Objects are manipulated using methods instead of traditional functions. In ooRexx, a string variable is a reference to a string ...
The following presents examples for one of the most widely used object-oriented languages, Java, which should cover nearly every way that an object-oriented language can treat this problem. Unlike in C++, objects in Java are always accessed indirectly through references. Objects are never created implicitly but instead are always passed or ...
Non-interpolated strings may also escape sequences, in which case they are termed a raw string, though in other cases this is separate, yielding three classes of raw string, non-interpolated (but escaped) string, interpolated (and escaped) string. For example, in Unix shells, single-quoted strings are raw, while double-quoted strings are ...
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.
The class keyword can also be used in the form Class.class to get a Class object without needing an instance of that class. For example, String.class can be used instead of doing new String().getClass(). continue Used to resume program execution at the end of the current loop body.
