An array data structure can be mathematically modeled as an abstract data structure (an abstract array) with two operations get(A, I): the data stored in the element of the array A whose indices are the integer tuple I. set(A, I, V): the array that results by setting the value of that element to V. These operations are required to satisfy the ...
The actions of type conversion in Eiffel, specifically converts to and converts from are defined as: A type based on a class CU converts to a type T based on a class CT (and T converts from U) if either CT has a conversion procedure using U as a conversion type, or CU has a conversion query listing T as a conversion type

For example: int a[2][3]; This means that array a has 2 rows and 3 columns, and the array is of integer type. Here we can store 6 elements they will be stored linearly but starting from first row linear then continuing with second row. The above array will be stored as a 11, a 12, a 13, a 21, a 22, a 23.

If two attributes participate in ordering, it is sufficient to name only the major attribute. In the case of arrays, the attributes are the indices along each dimension. For matrices in mathematical notation, the first index indicates the row , and the second indicates the column , e.g., given a matrix A {\displaystyle A} , the entry a 1 , 2 ...
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.
Insertion sort is very similar in that after the kth iteration, the first elements in the array are in sorted order. Insertion sort's advantage is that it only scans as many elements as it needs in order to place the k + 1 {\displaystyle k+1} st element, while selection sort must scan all remaining elements to find the k + 1 {\displaystyle k+1 ...
