Write Once, Run Anywhere.
Java technology is an object-oriented, platform-independent, multithreaded programming environment. It is the foundation for many Web and networked services, applications, platform-independent desktops, robotics, and other embedded devices.
Three main technology values of Java include:
A Richer User Experience - Whether you're using a Java technology-powered mobile phone to play a game or to access your company's network, the Java platform provides the foundation for true mobility. The unique blend of mobility and security in Java technology makes it the ideal development and deployment vehicle for mobile and wireless solutions. -
The Ideal Execution Environment for Web Services - The Java and XML languages are the two most extensible and widely accepted computing languages, providing maximum reach to everyone, everywhere, every time, to every device and platform. -
Enabling Business from End to End - Java technology offers a single, unifying programming model that can connect all elements of a business infrastructure.

JDK Java Developer's Kit
The Java SDK is a powerful toolkit that enables developers to build high-performance, secure, and scalable applications. Whether you're working on enterprise solutions, cloud-native applications, or AI-driven platforms, Java SDK provides cutting-edge tools to support your development journey.
Java SDK is a group of technologies and tools used in software development.
The Java Software Development Kit (JDK), also known as the Java Development Kit (JDK), is a comprehensive environment for building Java applications. It includes essential tools such as the Java compiler, debugger, runtime environment, and libraries that enable developers to create robust and scalable applications.

Java Compiler (javac)
- Converts Java source code into bytecode for execution on the Java Virtual Machine (JVM).
- Ensures syntax validation and optimization for efficient performance.
Java Virtual Machine (JVM)
- Executes compiled Java bytecode across different platforms.
- Supports Just-In-Time (JIT) compilation for runtime optimization.
Java Runtime Environment (JRE)
- Provides libraries and components required to run Java applications.
- Includes Garbage Collection (GC) for memory management.

Java Debugger (jdb)
- Enables step-by-step debugging of Java applications.
- Supports breakpoints, variable inspection, and stack tracing.
Java Archive Tool (jar)
- Packages Java classes and resources into a JAR file for distribution.
- Supports compression and digital signatures for security.
Java Documentation Generator (javadoc)
- Generates HTML-based documentation from Java source code comments.
- Helps developers maintain structured API references.

Apache Maven
- Automates build processes, dependency resolution, and project management.
- Supports plugin-based architecture for extensibility.
Gradle
- A flexible build system optimized for Java and Android development.
- Enables incremental builds and dependency resolution.

Java Security Manager
- Defines access control policies for Java applications.
- Prevents unauthorized operations and security breaches.
Garbage Collection (GC) Optimization
- Uses G1, ZGC, and Shenandoah GC for efficient memory management.
