map framework in Java
There are three primary ways of implementing the map framework in Java:
Hash Map: This JAVA Framework allows the implementation of hash table data structures. Elements in Hash Maps are stored in key/value pairs.
TreeMap: This JAVA framework allows the implementation of tree data structures. It provides accessibility to the Navigable Map interface.
LinkedHashMap: This framework allows the implementation of linked lists and hash tables. It extends to the HashMap class where its entries are stored in a hash table.
Stack, queueing and sorting using JFC: In Java Foundation Classes (JFC), stacks are abstract linear data types with predefined boundaries or capacities. They follow a certain order when adding or deleting elements. In linear data structures, components are organized in a straight line, meaning, if one removes or adds an element, the data structure will decrease or increase respectively. Stacks follow a LIFO (Last In First Out) or (FILO) First In Last Out technique of sorting elements, meaning, the last item is always the first one to be removed.
Graph structures and algorithms
Graphs are non-linear data structures comprising of nodes and edges. Sometimes, the nodes are also called vertices. Edges are simply the arcs or lines that connect nodes within the graph. In Java Assignment Help, graph algorithms are a given set of instructions that connect nodes together. Based on the type of data, an algorithm can be used to identify a specific node or even a path between two nodes. Graphs are important in modeling and solving real-world problems Linear and non-linear searching algorithms. Searching is a common action in business applications. It involves fetching the information stored in data structures like maps, lists, arrays, etc. to help the business in decision-making. In most cases, the search action determines how responsive a given application will be for the end-user. Programs written in Java use several types of search algorithms, the most common being linear and non-linear searching algorithms. The linear algorithm is used to identify elements in an array by looping over other elements of the array. The non-linear algorithm is mostly used with sorted arrays to identify various elements and usually returns the index of the found elements or a negative one if there is no index found.
RandomAccessFile
The Random Access File is a class in Java And Java Assignment Help used to write and read random access files. Basically, a random access file acts as a relatively large array of bytes. File pointer, a cursor applied to the array is used to perform the read-write operations and this is done by moving the cursor. If the program reaches the end-of-file and the required number of bytes have not been reached, then an EOFException is performed. In Java And JAVA Assignment Help, the Random Access File supports several access modes, which include, the read mode and the read and write mode. To read a byte, one must implement the read () method, and this will read a byte located in a position that is currently directed by the file pointer.
