  1. What is Java API?

  2. Click here to watch the video

  3. What is Java API? Java consists of two major components, JRE and JDK Java JRE JDK

  4. What is Java API? JDK consists of three major components Compiler JVM APIs JDK

  5. What is Java API? A  Java compiler is a predefined program that converts the high-level, user-written code language to low-level, computer-understandable, byte-code language during the compile time Java Compiler

  6. What is Java API? JVM(Java Virtual Machine) processes the byte code obtained from the compiler and generates an output in user-readable format JVM

  7. What is Java API? Like JVM and Compiler, Java APIs are integral software packages that come along with JDK. The primary intention of API is to establish communication between applications Java API

  8. What is Java API? Java Program Interpreter Java Program Java API JVM Application Hardware Fundamental Components of Java API

  9. What is Java API? Types of Developers using various types of APIs Partner Developers Open Developers Internal Developers

  10. What is Java API? Types of Developers using various types of APIs Leading Companies provide access to their APIs as Open-Source through authentication via a Unique Secret Key to keep track and ensure legal usage Open Developers

  11. What is Java API? Types of Developers using various types of APIs Open Developers include: B2C Team Open Developers

  12. What is Java API? Types of Developers using various types of APIs Internal Developers belong to a specific organization working in a closed environment. They use APIs with high Security that can establish communication and has access to only the Organization personnel Internal Developers

  13. What is Java API? Types of Developers using various types of APIs Internal Developers include: B2C Team B2B Team A2A Team B2E Team Internal Developers

  14. What is Java API? Types of Developers using various types of APIs Partner Developers are like Internal Developers. The only difference is, there are two or more organizations in collaboration with each other while accessing the resources and API Partner Developers

  15. What is Java API? Types of Developers using various types of APIs Partner Developers include: B2C Team B2C Team Partner Developers

  16. Need for Java API

  17. Need for Java API Create Powerful Apps Streamline Operations Improve Business

  18. Need for Java API Leading social Media applications, Delivery, and F and B applications are running smooth and hassle-free because of significant improvement by implementing APIs Streamline Operations

  19. Need for Java API Introducing APIs to the public leads many companies to release private data to generate new ideas, fix existing bugs, and receive new ways to improve operations Improve Business

  20. Need for Java API Online banking has changed the industry forever, and APIs offer customers the ability to manage their finances digitally with complete simplicity Create Powerful Apps

  21. Types of Java API

  22. Types of Java API There are mainly four types of APIs in Java as shown below Java API Composite Public Private Partner

  23. Types of Java API Public (or open) APIs  are Java APIs that come with the JDK. They do not have strict restrictions about how developers use them Public

  24. Types of Java API Private (or internal) APIs are developed by a specific organization and are accessible to only employees who work for that organization Private

  25. Types of Java API Partner APIs are considered to be third-party APIs and are developed by organizations for strategic business operations Partner

  26. Types of Java API Composite APIs are microservices, and developers build them by combining several service APIs Composite

  27. Data API and Services

  28. Data API and Services Data and API services are another way to categorize Java APIs other than public, private, partner, and composite. APIs are also classified based on their data-manipulation capabilities and the variety of services they offer Data API and Services

  29. Data API and Services Internal API Services External API Services Data API and Services CRUD Operations UI Services

  30. Data API and Services Internal API Services Internal API services are developed to offer organizations services specific to that organization. These services include only complex data operations and internal processes Data API and Services

  31. Data API and Services External API Services External APIs are open-source APIs that developers integrate into an existing application or website Data API and Services

  32. Data API and Services CRUD Operations CRUD APIs provide data manipulation operations over various data storage units such as SaaS and RDBMS, using standard storage-unit connecting tools like JDBC Data API and Services

  33. Data API and Services UI Services User interface service APIs are open-source APIs that allow developers to build user interfaces for mobile devices, computers, and other electronics Data API and Services

  34. API Service Protocols

  35. API Service Protocols The rules and protocols guide the functionality of the Java API. Different APIs have different service protocols. Let’s consider an example of RESTful API service protocol as an example

  36. API Service Protocols • Stateless • Uniform interface • Client-server • Cache • Layered

  37. API Service Protocols Since the RESTful API follows client-server architecture by default, it is recommended that the RESTful API Services to be stateless all the time Stateless

  38. API Service Protocols The entities in a RESTful API are the server and clients. Applications that run on a global scale need a client and server interface through HTTP. URI allocates the resources  Uniform Interface

  39. API Service Protocols The client-server model used in the RESTful API should be fault-tolerant. Both the client and server are expected to operate independently Client-Server

  40. API Service Protocols Including a cache memory allows the application to  record  intermediate responses and run faster in real time. A RESTful API also includes the cache memory Cache

  41. API Service Protocols A RESTful API is built using layers that are loosely coupled, or independent, from each other. Each layer contributes to a different level of hierarchy and supports encapsulation Layered

  42. Commonly used APIs

  43. Commonly used APIs API Acronym Web API None Facebook.4j None Twitter.4j None Android API Google Java Advanced Imaging JAI Java Data Objects JDO

  44. Commonly used APIs API Acronym RESTful API none Java Media Frameworks JMF Java Persistence API JPA Java Speech API JSAPI Java 3D J3D Java USB for Windows none
