Other interesting Programming Language alternatives to Java are JavaScript, C++, C# and Rust.
Python is an interpreted, interactive, object-oriented, extensible programming language. It provides an extraordinary combination of clarity and versatility, and is free and comprehensively ported.
JavaScript (sometimes shortened to JS) is a lightweight, interpreted, object-oriented language with first-class functions, most known as the scripting language for Web pages, but also used in many non-browser environments.
C++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose, powerful programming language. It is regarded as an intermediate-level language, as it comprises a combination of both high-level and low-level language features.
C# is a multi-paradigm programming language encompassing strong typing, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines.
Rust is a multi-paradigm, general-purpose programming language that emphasizes performance, type safety, and concurrency. It enforces memory safety—meaning that all references point to valid memory—without a garbage collector.
Open-source scripting language executed on the server, PHP embeds into HTML, fostering dynamic web development. Influenced by C, Java, and Perl, it supports database integration, offers extensive libraries, and remains easy for beginners while robust for seasoned developers.
C is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs.
Open-source programming language by Google, offering C-style syntax and automatic memory management. Features built-in concurrency and vast libraries, ideal for cloud services, web, and CLI development, supporting DevOps with fast builds and an expansive ecosystem.
Ruby is a dynamic, reflective, general purpose object-oriented programming language that combines syntax inspired by Perl with Smalltalk-like features. Ruby originated in Japan during the mid-1990s and was initially developed and designed by Yukihiro "Matz" Matsumoto.
Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference. Kotlin is designed to interoperate fully with Java, and the JVM version of its standard library depends on the Java Class Library, but type inference allows its syntax to be...
Scala is a modern multi-paradigm programming language based on the Java Virtual Machine (JVM) designed to express common programming patterns in a concise, elegant, and type-safe way.
