Is Java Going Away Anytime Soon? Don‘t Bet On It

Before we dive deeper into the details, let‘s get this out of the way upfront – Java is not going anywhere. As one of the most widely used programming languages worldwide for over 25 years now, Java continues to go from strength to strength. This article will make the case for why Java still dominates in 2022 across industries, remains actively developed, and is very much worth learning as a new programmer.

A Thorough History of Java‘s Evolution

Let‘s start at the beginning. Java was created in 1991 by James Gosling at Sun Microsystems, originally called "Oak" and was designed for programming interactive TV systems. The goals were to create a language that was:

• Platform independent – Write once, run anywhere
• Object-oriented – Simulate real-world entities as objects
• Familiar syntax – Based on C/C++ for easier adoption
• Distributed – Support networking and coordination between systems
• Secure – Built from the ground up with robust security
• Architecture neutral – Works on any hardware and OS
• Portable – Avoids hardware specific features
• Interpreted – Runs on a virtual machine for portability
• High performance – Yields fast, efficient compiled bytecode
• Multithreaded – Smooth concurrent, asynchronous execution
• Dynamic – Can load code modules at runtime

These design principles guided Java‘s initial release and continue to shape its evolution.

Some key milestones over Java‘s development history include:

• 1996 – JDK 1.0 released, followed quickly by JDK 1.1 with major improvements like inner classes, JavaBeans, RMI, JDBC API.

• 1998 – JDK 1.2 added Swing GUI toolkit, Collections framework, JIT compiler in HotSpot VM.

• 2000 – J2SE 1.3 was a major release, bringing the Collections API we know today, exception chaining, HotSpot JVM as default.

• 2004 – J2SE 5.0 introduced groundbreaking additions like generics, annotations, autoboxing, enums, variable argument lists.

• 2006 – Java was open sourced through the OpenJDK project to promote more open governance.

• 2011 – Java 7 brought try-with-resources, Project Coin syntax improvements, NIO2, Java Module System foundations.

• 2014 – Java 8 was a game changer, adding lambdas for functional programming, stream API, Date/Time API, default methods.

• 2017 – Java 9 adds the long-planned Java Module System through Project Jigsaw, improving security and maintainability.

• 2022 – The latest Java 19 features pattern matching for instanceof, new Vector API, virtual threads.

As this abbreviated timeline illustrates, Java has continued to evolve at a rapid pace for over 25 years while maintaining backwards compatibility. The major releases show how Java has grown far beyond its roots into an adaptable, modern language.

Java Remains Hugely Popular Among Developers

Beyond its active development path, Java‘s popularity according to various indices shows its enduring dominance:

• TIOBE Index for December 2022 – #3
• PYPL Popularity Index – #3
• IEEE Spectrum Ranking – #2
• RedMonk – #2

Some statistics that demonstrate its widespread usage:

• Used by 95% of Fortune 500 companies
• 9+ million developers use Java worldwide
• Runs on 3+ billion devices
• #1 most used backend language according to Stack Overflow
• Accounts for 17% of code on GitHub

Language	Ranking
Java	#1 Back-end, #2 Overall
JavaScript	#1 Overall
Python	#3 Overall

This data shows that Java remains among the top actively used programming languages globally. It is still widely taught in universities and bootcamps as a foundational language.

Large tech companies like Google, Facebook, Netflix, Uber, Twitter, Spotify, LinkedIn and SAP all rely on Java extensively for their backend infrastructure, big data processing, and mobile app development. Many are also major contributors to open source Java projects.

Simply put, Java has stood the test of time as one of the most relevant and in-demand languages for decades. And it has a huge ecosystem of libraries, tools, frameworks, and over 9 million developers worldwide.

Key Strengths That Made Java Dominant

What accounts for Java‘s enduring dominance and popularity over 25+ years? There are several major strengths and technical advantages that Java delivered, especially in its early days, that won over millions of developers:

• Platform independence – The JVM allows Java to run on any device, enabling usage from desktops, servers, mobile devices, embedded systems and more. C/C++ had a major weakness of needing platform-specific compilation.

• Object-oriented – Java provides a robust OO-model with polymorphism, inheritance and other key features for modeling large systems. Easy encapsulation for abstraction and modularity.

• Familiar C-like syntax – The C/C++-inspired syntax reduced the learning curve coming from C/C++. Programmers did not have to learn a completely alien programming paradigm.

• Memory management – The presence of automatic garbage collection in Java avoided the entire category of memory leaks and pointer security issues that plagued C/C++.

• Exception handling – Built-in exception handling avoided awkward error codes in favor of forcing clean error handling.

• Huge ecosystem – Sun and the Java community built extensive libraries, tools and frameworks in Java itself to leverage its strengths.

• Enterprise focus – Java‘s strengths aligned well with business systems – scalability, transactions, integration, concurrency.

• Security – Java‘s secure sandbox model, lack of pointers, bounds checking made it much more secure than C/C++.

• High performance – Just-in-time compilation and other tricks made Java surprisingly fast despite being "interpreted".

These characteristics allowed Java to surpass C++ and displace other languages to become the dominant backend enterprise language by the early 2000s. While other languages have since caught up, Java retains many of these advantages.

Drawbacks and Weaknesses of Java

Of course no language is perfect, and Java has also accrued its fair share of criticism over the years. Some of the typical complaints about Java include:

• Verbose, boilerplate code – Java typically requires more lines of code and ceremony compared to dynamic languages.

• Steep learning curve – Java‘s static typing, classes/interfaces, compilation add complexity for beginners versus scripting languages.

• Limited metaprogramming – Reflection is available but runtime modification of code isn‘t a key strength.

• Outdated – Some Java syntax and APIs seem outdated versus newer languages like Python.

• Not functional enough – Java 8 added lambdas, but functional programming is still not idiomatic.

• Not compiled to native – Platform independence means it can‘t be compiled to native machine code for performance like C/C++ can.

• Version fragmentation – Slow adoption of new versions leads to software running outdated Java versions.

• Vendor dependence – Tied to Oracle‘s implementation, though OpenJDK helps provide open governance.

As an enterprise-focused language, Java deliberately trades off some developer convenience for robustness and maintainability at scale. However, the language has continued to close this gap with each release.

How Does Java Compare to Other Major Languages?

Let‘s compare Java to some key alternatives like Python, JavaScript, C# and Kotlin:

	Java	Python	JavaScript	C#	Kotlin
Usage	Backend, Mobile, Big Data, Enterprise	Data Science, ML, Scripting	Frontend, Full-stack, Mobile	Cross-platform, Enterprise	Backend, Android
Speed	Very Fast	Slow	Fast	Fast	Fast
Learning Curve	Moderate	Easy	Moderate	Moderate	Easy
Ecosystem	Massive	Massive	Massive	Large	Smaller
Static Typing	Yes	No	Weak	Yes	Yes
Concurrency	Great	OK	OK	Great	Great
Code Readability	OK	Great	OK	OK	Great

As we can see, each language has advantages that make them appropriate for different domains. Java offers speed, robustness and portability while Python provides ease of use and development. JavaScript dominates frontend work while C# offers similarities to Java from Microsoft. Kotlin simplifies coding on the JVM.

In practice, knowing both Java and Python is tremendously valuable as their strengths are complementary. But Java remains ideal for large enterprise backend systems and platforms requiring scale, performance and stability.

Why Java Will Endure For Key Industries

Beyond generally popularity and technical strengths, Java dominates specific domains that rely heavily on its capabilities:
