It is difficult to say for certain whether Kotlin will completely replace Java in the next 10 years. Java has been the primary programming language for Android app development for many years, and has a large and established developer community. It is also used in many other areas such as enterprise software development and big data processing.
However, Kotlin has gained a lot of popularity in recent years, especially in Android app development. Google officially announced in 2017 that Kotlin is an officially supported language for Android app development. This means that Kotlin will play a big role in the future of android app development.
Kotlin offers many features that make it a more modern and efficient alternative to Java, such as null safety, extension functions, and coroutines. These features make it more efficient, expressive and easier to use than Java. As a result, many developers are moving to Kotlin and companies are also starting to adopt Kotlin for their projects.
It’s likely that Kotlin will continue to grow in popularity in the next 10 years, but it’s hard to predict whether it will completely replace Java. It is possible that Java will continue to be used in certain areas and Kotlin will be used in others, or that the two languages will coexist and be used together in different projects.
In summary, Kotlin is a powerful and modern language that has gained a lot of popularity in recent years and it’s likely that it will continue to grow in popularity in the next 10 years, but it’s hard to predict whether it will completely replace Java.
