Java's three-decade journey shows no signs of slowing down; it remains robust and remains a prevalent presence in the tech world.
Java, a widely used programming language, marked its 30th anniversary recently, showing no signs of aging. Developed by James Gosling at Sun Microsystems in 1995, Java was ideally suited to the growing interactivity and multimedia needs of the internet era.
Originally part of a project called 'Oak' aimed at revitalizing interactive television, Java was slightly ahead of its time initially. However, with the rise of the web and increased networking requirements, its creators foresaw the potential issues less portable languages might create in the future.
In an interview with our platform in 2007, Gosling noted that many of the ideas discussed back then had already come to fruition, although they seemed like extreme science fiction at the time.
So, what keeps Java relevant three decades later?
Java's enduring allure
Java is a high-level, general-purpose, object-oriented programming (OOP) language with a syntax resembling C/C++. Its popularity stems from its reliability, ease of use, and developer-friendly approach.
From its first public release (Java 1.0) in 1996 to 2001, more than 2.5 million developers worldwide incorporating Java into their daily tasks. Today, it powers numerous popular websites and applications we use routinely and remains the preferred language for many Android developers.
According to the 2024 State of the Developer Ecosystem report by JetBrains, 30% of developers named Java as their primary language. Last year's research indicated a resurgence of interest in the programming language, with enterprises planning to recruit more Java developers.
Further evidence of investment in Java development comes from the 2023 Java Developer Productivity Report from Perforce, which showed that nearly two-thirds (60%) of respondents planned to hire additional developers specializing in the language.
Java's demand among developers has remained relatively stable over the years, albeit with a peak in the early 2000s. Despite its age, Dewan Ahmed, principal developer advocate at Harness, stated that Java still plays a vital role in underpinning the tech stacks of global enterprises.
"Java may be turning 30, but it's far from showing its age - as it continues to support much of modern software development," Ahmed said. He noted that Java's longevity is due to its balance of consistent backward compatibility and continuous evolution, as well as the Java Virtual Machine's "write once, run anywhere" principle and syntax that has evolved over the years.
Moreover, Ahmed pointed out that Java's relevance is partly due to enterprise frameworks such as Spring Boot and Jakarta EE, ensuring that it remains relevant in the age of cloud-native and microservices architectures. "This wide ecosystem of libraries and tools, combined with widespread enterprise adoption, gives Java a staying power that newer languages struggle to match," Ahmed said.
Java in the era of memory safety
One significant advantage of Java at the age of 30 is its memory safety. With repeated warnings from security agencies about the dangers of memory-unsafe programming languages, Java's safety remains a crucial factor.
Languages like C and C++ suffer from a key weakness: they are vulnerable to bugs exploitable by attackers. Common vulnerabilities include buffer overflow weaknesses, out-of-bounds read/write flaws, and other memory-related issues.
These underlying memory weak points can be manipulated by malicious actors to cause damage. For instance, Google's analysis from 2023 suggested that about three-quarters of CVEs used in zero-day exploits targeted memory safety flaws.
The future of Java
Ahmed believes Java's long-term relevance hinges on its ability to adapt to AI, cloud, and edge computing. Progressive initiatives like Project Panama, for example, aim to make AI workloads more efficient on hardware resources. In the cloud, ahead-of-time compilation via GraalVM is poised to become more prevalent, while advanced garbage collectors like ZGC and Shenandoah promise to minimize pause times for latency-sensitive applications like real-time analytics.
These capabilities ensure that Java remains performant in modern, distributed environments, ensuring its continued relevance in an AI-centric future.
