Java vs Scala: What are the differences?
Developers describe Java as "A concurrent, class-based, object-oriented, language specifically designed to have as few implementation dependencies as possible". Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!. On the other hand, Scala is detailed as "A pure-bred object-oriented language that runs on the JVM". Scala is an acronym for “Scalable Language”. This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission critical systems, as many companies, including Twitter, LinkedIn, or Intel do. To some, Scala feels like a scripting language. Its syntax is concise and low ceremony; its types get out of the way because the compiler can infer them.
Java and Scala can be categorized as "Languages" tools.
"Great libraries", "Widely used" and "Excellent tooling" are the key factors why developers consider Java; whereas "Static typing", "Jvm" and "Pattern-matching" are the primary reasons why Scala is favored.
Scala is an open source tool with 11.8K GitHub stars and 2.75K GitHub forks. Here's a link to Scala's open source repository on GitHub.
According to the StackShare community, Java has a broader approval, being mentioned in 2399 company stacks & 2723 developers stacks; compared to Scala, which is listed in 437 company stacks and 324 developer stacks.
