Java is a widely-used and established programming language that has been around for over two decades, it has a large and active community, and it’s the primary language for android development and it’s widely used in enterprise systems. Java has a vast ecosystem and a lot of legacy code, it’s unlikely that Java will become redundant in the near future.
Kotlin, on the other hand, is a more modern and expressive language that was designed to improve the development experience for developers, it’s also the official language for Android development, recommended by Google. Kotlin is fully interoperable with Java, which means that Java developers can continue to use their existing Java codebase, libraries, and frameworks while gradually incorporating Kotlin into their projects.
It’s important to note that Kotlin and Java are not mutually exclusive, and both languages can coexist and complement each other. Java developers can continue to use Java for existing projects and also start using Kotlin for new projects, as well as for android development. Additionally, Kotlin can be used for web development and server-side development, which are areas where Java is widely used.
In summary, Java is a widely-used and established programming language that has a large and active community, a vast ecosystem and a lot of legacy code, it’s unlikely that Java will become redundant in the near future.
