Is Java As Relevant As Ever? Moreso?

To gather insights on the state of the Java ecosystem today, we spoke to nine executives who are familiar with the ecosystem. 

We asked experienced Java professionals, "What are real-world problems being solved by Java today?" Here's what they told us:

• Backend infrastructure is all Java. It does all the heavy lifting with business solutions, Big Data, and analytics. The banks run on Java.
• Embedded Java is underrepresented in most conversations. We are solving virtually all problems in billions of devices in industries like telecom, banking, and healthcare.
• All major systems filing patents, every step going through reviews, collecting fees, granting of trademarks are with Angular JS. ACA is all Java. Hub verification testing is powered by Java. 
• The most interesting thing we’re seeing is the alternate .NET platforms like Xamarin, .NET Core, and .NET Standard.
• Evolution is moving away from heavy J2E to lightweight. Android Studio is based on IntelliJ – the most popular IDE.
• The ability to write code for mobile applications that provide a great user experience.
• Enterprise-level microservices from the Java monolith to Java microservices.
• There's a lot of Java in the world. Solutions are packaged into the Java app – an agent focused on security. Automated prevention of attacks. We see interesting attacks and can see people going into the database. We can provide the key risk map and provide a targeted way to fix SQL injection in production into the application.
