for (name in phonebook) {print name," ", phonebook [name]} The user can search for elements in an associative array, and delete elements from the array. The following shows how multi-dimensional associative arrays can be simulated in standard AWK using concatenation and the built-in string-separator variable SUBSEP:
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.
GENERIC is more complex, based on the GCC 3.x Java front end's intermediate representation. GIMPLE is a simplified GENERIC, in which various constructs are lowered to multiple GIMPLE instructions. The C, C++, and Java front ends produce GENERIC directly in the front end. Other front ends instead have different intermediate representations after ...
The Java language has provided genericity facilities syntactically based on C++'s since the introduction of Java Platform, Standard Edition (J2SE) 5.0. C# 2.0, Oxygene 1.5 (formerly Chrome) and Visual Basic (.NET) 2005 have constructs that exploit the support for generics present in Microsoft .NET Framework since version 2.0.
Generics in Java are a language-only construction; they are implemented only in the compiler. The generated classfiles include generic signatures only in form of metadata (allowing the compiler to compile new classes against them). The runtime has no knowledge of the generic type system; generics are not part of the Java virtual machine (JVM).

C++ changes some C standard library functions to add additional overloaded functions with const type qualifiers, e.g. strchr returns char* in C, while C++ acts as if there were two overloaded functions const char *strchr(const char *) and a char *strchr(char *). In C23 generic selection will be used to make C's behaviour more similar to C++'s. [11]
Elements can be removed from the end of a dynamic array in constant time, as no resizing is required. The number of elements used by the dynamic array contents is its logical size or size, while the size of the underlying array is called the dynamic array's capacity or physical size, which is the maximum possible size without relocating data.
