In java buzz are important these are the building blocks of java

Platform Independence: Java is designed to be platform-independent, meaning that Java code can run on any device that has a Java Virtual Machine (JVM) installed.

Object-Oriented Programming (OOP): Java is an object-oriented programming language, emphasizing the use of classes and objects to structure code and promote code reusability.

Write Once, Run Anywhere (WORA): This concept is closely tied to platform independence, indicating that Java code can be written once and executed on any device without modification.

JVM (Java Virtual Machine): The JVM is a key component of Java’s platform independence, providing an execution environment for Java bytecode on different platforms.

Garbage Collection: Java includes an automatic memory management system that takes care of deallocating memory, known as garbage collection. Developers don’t need to manually free up memory.

Multithreading: Java supports multithreading, allowing the execution of multiple threads concurrently. This is essential for building scalable and responsive applications.

Exception Handling: Java has a robust exception handling mechanism that helps manage and recover from runtime errors, enhancing the reliability of applications.

Annotations: Annotations provide metadata about the code and are used for various purposes, such as adding information to classes, methods, or fields.

Java API (Application Programming Interface): The extensive Java API provides a set of libraries and classes that developers can use to build various types of applications.

Synchronization: In the context of multithreading, synchronization ensures that multiple threads can safely access shared resources without conflicts.

Applet: Although less commonly used today, Java applets were small applications that could be embedded in web pages to provide interactive content.

Swing and JavaFX: These are Java’s GUI (Graphical User Interface) libraries, used to create desktop applications with rich user interfaces.

Spring Framework: While not a core part of Java itself, Spring is a widely used framework for building enterprise-level Java applications, providing features such as dependency injection and aspect-oriented programming.
