Automatic Memory Allocation and Deallocation using Garbage Collector

Java was designed to be cross-platform (even to run on toasters) and is probably the most used programming language in business. It is very similar to a beginner's version of C++ with the more complicated features removed, and despite the name, it has nothing to do with Javascript. Java is object orientated and you have to use classes in order to program in it. Java is not compiled but is instead a virtual machine that uses a bytecode, which is called the JVM (Java Virtual Machine), and runs code from a JAR (Java Archive) file. Java uses exceptions to indicate errors, some exceptions must be handled by the code and you use to try and catch to deal with them. Unlike C, it handles the memory allocation and deallocation automatically using a garbage collector, which means when you no longer need the memory it can be freed automatically.

I/O with byte and character streams

Java carries out input and output operations through an abstraction process called a stream. Streams in Java are in two basic types; the byte stream and the character stream, with each type performing a specific task. The byte stream, as the name suggests, handles the input and output of bytes. The character stream, on the other hand, handles the input and output of characters. The byte stream manages 8-bit bytes of binary data and the character stream handles 16-bit Unicode characters. When Java was introduced, it didn’t have character streams, all input and output functions were byte-oriented. The invention of character streams in subsequent versions of Java made the language more efficient and convenient in terms of handling data streams.

Map framework

The Java map framework is organized on the basis of keys. Each map contains a key and value pair, commonly referred to as the entry, and each key is unique based on the data it represents. Maps allow users to search, delete, or update various elements using keys. There are three primary ways of implementing the map framework in Java:

HashMap:

This framework allows the implementation of hash table data structures. Elements in HashMaps are stored in key/value pairs.

TreeMap:

The TreeMap framework allows the implementation of tree data structures. It provides accessibility to the NavigableMap 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. Queues are also linear data structures but a little different from stacks in that they follow a different method of sorting components. Elements in a queue follow the FIFO (First In First Out) order and are open on both ends. One end is used for adding data and the other one is used for removing data. Stacks have only one open end.

Height balanced binary search tree, heap tree, and Huffman tree

In Java, a Binary Search Tree, commonly abbreviated as BST, is a node-based data structure in which the left subtree of each node has lesser keys than the main node and the right subtrees have more keys than the main node. A heap tree is a unique type of binary tree in which the root node is lesser than all the other nodes contained in the heap. In other words, the value of each and every internal node is smaller or sometimes equal to the value of its child nodes. The Huffman, or Huffman coding tree, is a complete binary tree in which every leaf contained in the tree matches a letter in a given alphabet. The binary search tree, heap tree, and Huffman tree are some of the most important concepts of Java and play a huge role in enhancing software development.

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, 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. By applying various algorithms, graphs can be used to rectify issues in state machine modeling, social network sites, and many other areas. Some of the most commonly used graph algorithms today include Depth First Search, Breadth-First Search, Floyd-Warshall, and Dijkstra.

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 RandomAcessFile is a class in Java 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, the RandomAcessFile 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.

Java Applet programming

An Applet is a special program that is integrated into Java webpages to create dynamic content. This program has plenty of advantages; for instance, it is secure, can run on many different platforms (Windows, macOS, Linux, etc.), and since it runs on the client-side, it also has less response time. The lifecycle of an Applet consists of the following stages:

init:

Meant to initialize the applet. It is only called once the param tags contained in the Applet tags have been executed and processed.

start:

Started after the browser has initialized the Applet.

stop:

Initiated when the user leaves the page where the Applet sits.

destroy:

This process is initiated when the browser closes normally.

paint:

Called immediately after the start process and any time the browser repaints itself in the browser.

AWT programming

Short for Abstract Window Toolkit, AWT is an application programming interface for developing graphical user interfaces and window-based programs and applications in Java. The components in Java AWT are platform-independent, meaning, they are displayed based on the operating system on which they are running. This preserves the look and feel of the platform. While this is a huge advantage, it can also be a disadvantage in that a GUI created for one platform may display and look differently when run on a different platform. The Abstract Window Toolkit is heavyweight, that is, the components rely on the resources provided by the operating system to function.

Networking in Java

Java networking basically involves linking multiple computers together in order to share resources. To achieve this, a Java program is installed to communicate with numerous computers at the application layer. There are two major protocols involved in Java networking:

Transmission Control Protocol (TCP):

This protocol enables two or more applications to communicate reliably. When TCP is used over the network, it is referred to as TCP/IP.

User Datagram Protocol (UDP):

This is a connection-less protocol that enables the network to transmit packets of data between applications.
The main idea behind Java networking is to share resources and allow for effective centralized software management.

Swing

Java Swing is a graphical user interface widget toolkit for Java that contains an extensive library of widgets. It is one of the components of Java Foundation Classes and comes with numerous packages for creating robust programs and applications in Java. The toolkit consists of built-in controls such as image buttons, trees, sliders, tabbed panes, color choosers, toolbars, tables, and text boxes for displaying HTTP and rich text format files. Since all Swing components are written in Java, they are platform-independent. This particular feature enables programmers to create applications in Swing easily and more conveniently, as one program can be created to run on many different platforms, and this improves the overall development time. And since JDBC offers the same capabilities ODBC does, the resulting Java programs are able to maintain a database-independent code.

JDBC

Java Database Connectivity (JDBC) is a Java application programming interface used to create a database-independent link between the programming language and databases. It is technically a library and contains application programming interfaces for performing specific tasks including creating a link to databases, writing MySQL and SQL statements, executing MySQL and SQL queries in the database, and viewing and modifying records. Programmers use Java to create a host of executables such as Applets, applications, Servlets, Enterprise JavaBeans, and Java server pages, and all these executables use JDBC to access the underlying database and use the stored data.

Java Based Book Database

The program needs to use JDBC. The database should be a list of books with authors. Select an author and list all the books by the author. The books should be listed chronologically, and include the title and year. There should be at least 2 more queries that would be useful. Create a GUI to view and edit the database. Created an indexed list that uses lists for each letter to speed up searching.

Multithreaded simulation of Traffic

The code written in Java is a multithreaded simulation of traffic patterns with a GUI in Java. It multiple traffic lights and vehicles.

Sort using Stack in Java

The code sorts the values into order using 2 stacks (one for high values and one for low values).
