The document discusses the evolution and current innovations of Java, highlighting its prominence as the most used programming language and its applications in major platforms like Twitter and Airbnb. It covers Java's foundational goals, ecosystem, and future developments including GraalVM, Loom, and cloud-native frameworks like Quarkus. It underscores Java's ongoing relevance and adaptability in modern programming landscapes.

1. current innovations in the most
critical programming language: java
Hossein mahdavipour
Scientific seminars
Dr. Jahangir
Spring 2021

2. Today java
●
Most used programming language based on
tiobe index(march 4)1
●
Basis of Hadoop, Flink, Cassandra, Lucene,
Elasticsearch, Scala, closure, Netty
●
Twitter, Airbnb, Uber, LinkedIn, eBay2
●
Pinterest, Groupon, Spotify, Pandora, Square
on Java mostly2

3. past java
●
1995
●
Rivals: C, C++, VC++, Visual Basic, Python
●
Applets, JSP, Servlet, J2ME

4. Foundation Blocks of Java4
●
Build a simple, object-oriented language that would be
easy for C++ programmers.
●
Make it platform-neutral and architecture-neutral.
●
High performance with many in-memory features and
performance tuning with command line arguments.
●
Make it multi-threaded, dynamic, and interpreted.
●
Include security and robust features.

5. Java future road
●
Implementation vs specification
●
JCP: Java Community Process5
●
JEP: java enhancement process6

6. Java ecosystem

7. Java ecosystem: jdk vendors
●
AdoptOpenJDK
●
Alibaba (Dragonwell)
●
Amazon (Corretto)
●
Azul (Zulu, Zing)
●
BellSoft (Liberica)
●
Red Hat (Red Hat Builds of OpenJDK)
●
Oracle (Oracle JDK, Oracle OpenJDK)
●
SAP (SapMachine)

8. Future java: WIP
●
GraalVM
●
Loom
●
Valhala
●
GC
●
Cloud native: Quarkus

9. GraalVM
●
JIT in java
●
native images
●
Polyglot programing: Truffle
– Java, R, python, ruby, LLVM, webassembly,
javascript & nodejs
●
Running in Oracle Database

10. GraalVM

11. GraalVM
Image reference: reference 10

12. GraalVM
AOT + JIT
Image reference: reference 10

13. GraalVM
Image reference: reference 10

14. Loom
●
Motto: All Your Blocking Are Belong to Us
●
Event lope vs structured concurrency11
●

15. Valhalla
●
New primitive types
●
New generics system

16. GCs
●

●
Epsilon
●
Zgc: O(1) and 1 ms gc pause time.

17. Future java: cloud native
Image reference: reference 8

18. Future java: cloud native
●
Quarkus framework
– Build time vs runtime initializing
– Native image
– live reload

19. Future java: cloud native
