Socket (TCP & UDP) communication in Java

Socket communication in Java enables communication between two endpoints over a network. There are two main types of sockets: TCP sockets and UDP sockets. Let's explain both types with examples: TCP Socket Communication: 1. **Server Side**:    - The server creates a `ServerSocket` object to listen for incoming connections on a specific port.    - When a client connects, the server accepts the connection and creates a `Socket` object to communicate with the client.    - The server reads from and writes to the socket's input and output streams to communicate with the client. import java.io.*; import java.net.*; public class TCPServer {     public static void main(String[] args) throws IOException {         ServerSocket serverSocket = new ServerSocket(12345);         System.out.println("Server started. Waiting for client...");         Socket clientSocket = serverSocket.accept();   ...

OracleJDK vs OpenJDK



Oracle JDK (Java Development Kit): Oracle JDK is the official reference implementation of the Java Platform, Standard Edition (Java SE). It included the JRE along with development tools.

OpenJDK: An open-source alternative to Oracle JDK, OpenJDK is a community-driven project. It provides a free and open-source implementation of the Java Platform, and many other JDKs, including Oracle JDK, are derived from OpenJDK.


Below is a simple table highlighting some key points of comparison between Oracle JDK and OpenJDK:

FeatureOracle JDKOpenJDK
VendorOracle CorporationOpenJDK Community
LicensingCommercial (Paid) with Oracle Binary Code License AgreementOpen Source (GNU General Public License, version 2, with the Classpath Exception)
SupportCommercial support available with Oracle Support subscriptionCommunity support, may have commercial support options from other vendors
Updates and PatchesRegular updates with security patches provided by OracleUpdates and patches contributed by the open-source community
JavaFXBundled with Oracle JDK (until JDK 11)Separately available in OpenJFX for OpenJDK
Mission ControlBundled with Oracle JDK (until JDK 11)Separately available for OpenJDK
Flight RecorderRequires commercial subscription for full featuresOpen-source version available with OpenJDK
Commercial FeaturesSome features are commercial and require a subscriptionAll features are open source and freely available
Build ProcessProprietary build process for Oracle JDKOpenJDK build process is open and community-driven
Release CycleGenerally aligned with OpenJDK releasesOpenJDK sets the base for Oracle JDK releases
Long-Term Support (LTS)Oracle provides LTS releases with extended supportSome OpenJDK builds, like AdoptOpenJDK or Amazon Corretto, offer LTS support
Usage RestrictionsSome restrictions in Oracle JDK binary distributionOpenJDK has no usage restrictions
Java Cryptography Extension (JCE)Unlimited strength policy included by defaultMay require additional configuration for unlimited strength cryptography

Please note that the information provided here is subject to change, and it's always a good idea to refer to the official documentation of Oracle JDK and OpenJDK for the most up-to-date details.

Method Overloading in Java

Method Overloading in Java Method Overloading  is a feature in Java that allows a class to have multiple methods with the same name but different parameter lists. The methods can have a different number or types of parameters. The decision on which method to invoke is made by the compiler based on the arguments provided during the method call.  Example: public class Calculator {     // Method to add two integers     public int add(int a, int b) {         return a + b;     }     // Method to add three integers     public int add(int a, int b, int c) {         return a + b + c;     }     // Method to add two doubles     public double add(double a, double b) {         return a + b;     }     // Method to concatenate two strings     public String concatenate(String str1, String str2) {         ...

Java Runtime Environment (JRE)

Definition : Java Runtime Environment (JRE) is a set of software tools and libraries that enables the execution of Java applications. It provides the necessary runtime support for Java programs to run on various devices and platforms. Components of Java Runtime Environment (JRE): Java Virtual Machine (JVM): Definition: The JVM is a crucial component of the JRE responsible for executing Java bytecode. Functionality: It interprets Java bytecode or, in some cases, uses Just-In-Time (JIT) compilation to translate bytecode into native machine code for improved performance. Importance: JVM abstracts the underlying hardware, allowing Java programs to be platform-independent. Class Libraries: Definition: JRE includes a set of precompiled classes and methods that Java applications can utilize. Functionality: These classes cover a wide range of functionalities, from basic data structures to networking. Importance: Class libraries provide a foundation for developers, offering reusable code ...
