What are the advantages and disadvantages of the linked implementation of a queue relative to the contiguous implementation?
Contiguous implementation (e.g., using an array), has a major disadvantage in that you have to allocate enough space in the array to hold all the elements in the queue. When there is insufficient space, you have to re-allocate, which may occasionally require the entire array be copied to new memory. In addition, with each extraction, you are left with unused memory at the start of the array. Thus before any re-allocation, you must first check if there are unused elements and then shunt all elements forward, thus creating space at the end of the array. If we ignore the shunting and re-allocations necessary with an array, insertions and extractions will occur in constant time for both contiguous and linked implementations. However, once you take shunting and re-allocation into account, we find that contiguous implementations occasionally falter during an insertion. Contiguous implementations also require more memory than linked implementations. Although a linked node is larger than an array element by one pointer (32 bits on a 32-bit system), contiguous implementations must allocate far more memory than is actually required in order to minimise the number of re-allocations. Thus an array must always have unused elements. Moreover, when all elements are extracted from the queue, the current allocation remains in memory. With linked implementations, the only memory allocated is the memory actually in use at any given moment, with the minimum memory requirement being just one pointer, to the tail node. An optimal queue implementation will use a circular linked list, where only the tail node need be maintained by the list object. The tail's next node always points to the head node, so there is no need to maintain this separately. The only real disadvantage of a linked implementation is the need to allocate and deallocate memory for each insertion and extraction respectively. However, this is a constant time operation. With contiguous implementation, only extraction is guaranteed to be a constant time operation. Most of the time, insertions will be constant time, but will occasionally take variable time due to the need to shunt or re-allocate.
How do you sort the integer numbers of arraylist in java?
You can also use the Collections.sort() method to sort values in an array list. You can also use the Comparable Interface or Comparators for providing custom implementations of sorting algorithms for values inside an ArrayList.
Where can one learn about JSF implementations?
One can learn about JSF implementations, Of course on Java it's self. Another way one can learn about JSF implementations is at a public library one can look at a book related to the topic.

What is time requirement for insert operation one dimensional array state average and worst case time management?
The time-complexity of an insert operation upon an array is O(n-k), where n is the number of elements in the array (such that n>=0), and k is the position where the insertion will occur (such that k<=n). The time-complexity arises due to the need to move the last n-k elements in the array to make room for the new element. Thus inserting at or near the start of the array will take more time than inserting at or near the end of the array. Inserting at the end of an array is a constant-time operation, O(1). However, all of this presumes that the array has one or more unused elements at the end of the array to allow for expansion. If the array is full (no unused elements), the entire array must be re-allocated. For optimal performance, implementations will typically grow an array by increasing the allocation by 50% - 100%, thus time-complexity is said to be amortized rather than finite due to the occasional need to re-allocate. Note that the number of dimensions is immaterial since all arrays are intrinsically one-dimensional. That is; a two-dimensional array is nothing more than a one-dimensional array where every element is itself a one-dimensional array. The length of each element will affect the actual time taken to complete an insertion, however it does not affect the time-complexity.
Differentiate single dimensional array to double dimensional array?
A single dimensional array is an array of items. A two-dimensional array is an array of arrays of items.
What is meant by irregular dimensional array?
An irregular dimensional array is a special type of multi-dimensional array.First we must understand that a multi-dimensional array is just an array of arrays. Each element in the array is, itself, an array of elements.A regular multi-dimensional array will be an array of size n, with each element containing a separate array of size m. That is, each sub-array has the same size.An irregular multi-dimensional array will be a multi-dimensional array in which each sub-array does not contain the same number of elements.Regular array:array[0] = new array{0, 1, 2}array[1] = new array{3, 4, 5}array[2] = new array{6, 7, 8}array[3] = new array{9, 10, 11}This regular array is an array of size 4 in which each sub-array is of size 3.Irregular array:array[0] = new array{0, 1, 2}array[1] = new array{3, 4}array[2] = new array{5, 6, 7}array[3] = new array{8, 9, 10, 11}This irregular array is an array of size 4 in which the size of each sub-array is not the same.
How do you swap two adjecent no in array in c?
Option 1) Use a temporary variable: int x = array[i]; array[i] = array[i+1]; array[i+1] = x; Option 2) Use bit operators: array[i] ^= array[i+1] ^= array[i];
How do you swap rows in 2 dimensional array in Java?

What is array literal in as2?
An array literal is a comma-separated list of the elements of an array. An array literal can be used for initializing the elements of an array.
