Java remains a robust and widely used programming language with applications in diverse domains, from enterprise-level systems to Android app development. It provides cross-platform compatibility and strong security features, making it a preferred choice for building large-scale applications. Additionally, the Java Virtual Machine (JVM) enables Java code to run on different platforms, further extending its reach.

4. C#

C# (C Sharp) is primarily associated with Microsoft technologies and is the backbone of the .NET framework. With the rise of Xamarin, C# has become a popular choice for mobile app development across Android, iOS, and Windows platforms. Its versatility extends to game development, particularly with the Unity game engine. As Microsoft continues to invest in C# and .NET, its demand is set to increase.

5. Go
   

   (Golang)

Go, commonly referred to as Golang, has gained significant traction in recent years due to its simplicity, concurrency support, and efficient performance. Developed by Google, Go is well-suited for building scalable and high-performance applications, making it a preferred language for cloud-based and distributed systems. As the demand for cloud computing and microservices architecture grows, so does the demand for Go developers.

6. Kotlin

Kotlin is an open-source, modern programming language that runs on the Java Virtual Machine (JVM). It has gained prominence as the preferred language for Android app development, surpassing Java in terms of adoption. Kotlin’s concise syntax, enhanced safety features, and seamless interoperability with Java code make it a compelling choice for building Android applications.

7. Swift

Swift, developed by Apple, is the go-to language for iOS and macOS app development. Its intuitive syntax and performance optimizations have attracted developers, replacing Objective-C as the language of choice for Apple ecosystem development. With Apple’s constant focus on enhancing the iOS ecosystem, learning Swift opens up opportunities for creating innovative and user-friendly applications.

8. Rust

Rust is a relatively new systems programming language known for its focus on safety, concurrency, and high performance. Developed by Mozilla, Rust is gaining popularity for building applications that require low-level control without sacrificing safety. Its memory safety features prevent common programming errors like null pointer dereferences and buffer overflows, making it suitable for critical systems and security-sensitive applications.
