A bit array (also known as bitmask, [ 1 ]bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits. It can be used to implement a simple set data structure. A bit array is effective at exploiting bit-level parallelism in hardware to perform operations quickly. A typical bit array stores kw bits, where w ...
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.
where each n or v is a floating-point number in sign-mantissa-e-sign-exponent format, e.g., 2.648000e-002. The file concludes with: endsolid name An example ASCII STL of a sphericon. The structure of the format suggests that other possibilities exist (e.g., facets with more than one loop, or loops with more than three vertices). In practice ...

In computer science, an associative array, map, symbol table, or dictionary is an abstract data type that stores a collection of (key, value) pairs, such that each possible key appears at most once in the collection. In mathematical terms, an associative array is a function with finite domain. [ 1 ] It supports 'lookup', 'remove', and 'insert ...
Red–black trees are similar in structure to 2–3–4 trees, which are B-trees of order 4. [18] In 2–3–4 trees, each node can contain between 1 and 3 values and have between 2 and 4 children. These 2–3–4 nodes correspond to black node – red children groups in red-black trees, as shown in figure 3.
Space. Θ (n) [ 1 ] O (n) A small phone book as a hash table. In computing, a hash table is a data structure that implements an associative array, also called a dictionary or simply map; an associative array is an abstract data type that maps keys to values. [ 2 ] A hash table uses a hash function to compute an index, also called a hash code ...
Java Advanced Imaging. Java Advanced Imaging (JAI) is a Java platform extension API which allows developers to create their own image manipulation routines. JAI is provided as a free download directly from Oracle Corporation for the Windows, Solaris, and Linux platforms. Apple Inc. provides an OS X version of the API from their website for Mac ...
