Java

A concurrent, class-based, object-oriented, language specifically designed to have as few implementation dependencies as possible

Clojure is a dynamic, general-purpose programming language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming.

Java features and specs

Platform Independence
Java is known for its portability across multiple platforms via the Java Virtual Machine (JVM). This means you can write code once and run it anywhere.
Large Standard Library
Java boasts a comprehensive standard library, which facilitates development by providing pre-built solutions for a wide array of programming tasks.
Robust and Secure
Java emphasizes strong memory management and has built-in security features, making it a reliable choice for applications requiring high levels of security.
Community Support
With a vast and active community, ample resources are available for learning and troubleshooting. Numerous libraries and frameworks are available due to its long-standing presence.
Performance
Modern Java versions offer performance that is generally very good for many applications, particularly server-side applications where the Just-In-Time (JIT) compiler can significantly optimize runtime performance.

Possible disadvantages of Java

Verbosity
Java's syntax can be verbose compared to newer languages, requiring more lines of code to accomplish the same tasks, which may reduce readability.
Memory Consumption
Java applications can be memory-intensive due to their reliance on the JVM, which can be a downside for resource-constrained environments.
Performance Overhead
Despite its generally good performance, Java's reliance on the JVM introduces some overhead compared to languages that compile to native machine code, such as C++.
No Low-Level Programming
Java abstracts away from the hardware, making it less suitable for low-level programming tasks that require direct hardware manipulation, such as embedded systems programming.
Slow Startup Time
Java applications can have slower startup times due to the overhead of JVM initialization, which can be a drawback for desktop applications or command-line tools that are frequently started and stopped.

Clojure features and specs

Functional Programming Paradigm
Clojure emphasizes immutability and first-class functions, which can lead to more predictable and maintainable code.
Interoperability with Java
Clojure runs on the JVM, allowing seamless integration with the vast ecosystem of Java libraries and tools.
REPL Driven Development
Clojure's Read-Eval-Print Loop (REPL) allows for interactive programming, making it easier to test and debug code in real time.
Concise Syntax
Clojure's syntax is minimalistic and expressive, which can lead to more concise and readable code.
Concurrency Support
Clojure provides strong support for concurrent programming with features like Software Transactional Memory (STM) and immutable data structures.

Possible disadvantages of Clojure

Steep Learning Curve
The functional programming paradigm and Lisp-like syntax can be challenging for newcomers, particularly those from imperative programming backgrounds.
Performance Overhead
Clojure's emphasis on immutability can introduce performance overhead compared to languages that use mutable data structures.
Limited Tooling
While improving, the ecosystem for Clojure is not as mature as for some other mainstream languages, which can pose challenges in finding robust development and debugging tools.
Less Mainstream
Clojure is not as commonly used as languages like Python or Java, which can make it harder to find experienced developers or community support.
Verbose Error Messages
Error messages in Clojure can sometimes be verbose and difficult to understand, which can complicate the debugging process.

Can someone help with port forwarding?
You can use UPnP PortMapper. Source code/Download. All you need is Java and that's it. Hope this helps. Source: about 3 years ago
PolyGlot 3.5 Release
I would definitely suggest installing Java for this one, and the error should have asked you to do so. I'll have to look into why that was not popping properly for you and address it in a bug fix. In the mean time, you can address the issue by going here to install Java: https://java.com/en/. Source: over 3 years ago
i need help pls
Https://java.com/en/ Is this the java you're using to install optifine. When I first got optifine I thought java meant Minecraft and not java. Source: over 3 years ago
I keep getting this error when I try to install Worldpainter
I had this problem before just go to https://java.com/en/ and download the java then you will have to install the actual java, then after its installed go to This PC then Windows then Program Files then Java then go to the file name file name that show I think when you downloaded it then go into bin and you will find a java.exe file then click it and World Painter will install and that's who I solved king problem...

Create a Server Driven CLI from your REST API
Another project of mine Bob can be seen as an example of spec-first design. All its tooling follow that idea and its CLI inspired Climate. A lot of Bob uses Clojure a language that I cherish and who's ideas make me think better in every other place too. - Source: dev.to / 2 months ago
Scheming About Clojure
Clojure is a LISP for the Java Virtual Machine (JVM). As a schemer, I wondered if I should give Clojure a go professionally. After all, I enjoy Rich Hickey's talks and even Uncle Bob is a Clojure fan. So I considered strength and weaknesses from my point of view:. - Source: dev.to / 6 months ago
Moving your bugs forward in time
‍For the rest of this post I’ll list off some more tactical examples of things that you can do towards this goal. Savvy readers will note that these are not novel ideas of my own, and in fact a lot of the things on this list are popular core features in modern languages such as Kotlin, Rust, and Clojure. Kotlin, in particular, has done an amazing job of emphasizing these best practices while still being an... - Source: dev.to / 12 months ago
Let's write a simple microservice in Clojure
This article will explain how to write a simple service in Clojure. The sweet spot of making applications in Clojure is that you can expressively use an entire rich Java ecosystem. Less code, less boilerplate: it is possible to achieve more with less. In this example, I use most of the libraries from the Java world; everything else is a thin Clojure wrapper around Java libraries. - Source: dev.to / about 1 year ago
A new F# compiler feature: graph-based type-checking
I have a tangential question that is related to this cool new feature. Warning: the question I ask comes from a part of my brain that is currently melted due to heavy thinking. Context: I write a fair amount of Clojure, and in Lisps the code itself is a tree. Just like this F# parallel graph type-checker. In Lisps, one would use Macros to perform compile-time computation to accomplish something like this, I think.... - Source: Hacker News / over 1 year ago
