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.

Accessing Java fields, methods and types from the native code requires something similar to reflective programming (reflection). Signatures are specified in strings and queried from the JVM. This is both slow and error-prone. Java Strings are objects, have length and are encoded. Accessing or creating a string may require an O(n) copy.
Support for object-oriented programming. Modular libraries with autoloading on-demand facilities. Large base of core functions and classes. String and list processing. Regular expressions. File and network I/O. Database access. XML processing. 100% pure Java. The Tea interpreter is implemented in Java. Tea runs anywhere with a Java 1.6 JVM or ...
Java Native Access (JNA) is a community-developed library that provides Java programs easy access to native shared libraries without using the Java Native Interface (JNI). JNA's design aims to provide native access in a natural way with a minimum of effort. Unlike JNI, no boilerplate or generated glue code is required.
In computer programming, an indirection (also called a reference) is a way of referring to something using a name, reference, or container instead of the value itself. The most common form of indirection is the act of manipulating a value through its memory address. For example, accessing a variable through the use of a pointer.
Although reserved as a keyword in Java, const is not used and has no function. [2] [26] For defining constants in Java, see the final keyword. goto Although reserved as a keyword in Java, goto is not used and has no function. [2] [26] strictfp (added in J2SE 1.2) [4] Although reserved as a keyword in Java, strictfp is obsolete, and no longer ...
A basic example is in the argv argument to the main function in C (and C++), which is given in the prototype as char **argv—this is because the variable argv itself is a pointer to an array of strings (an array of arrays), so *argv is a pointer to the 0th string (by convention the name of the program), and **argv is the 0th character of the ...
