A Kotlin class necessitates less code than a Java class does for the same operation.įor example, a particular segment where Kotlin can significantly reduce the total amount of boilerplate code is findViewByIds. Code ConcisenessĬomparing a Java class with an equivalent Kotlin class demonstrates the conciseness of Kotlin code. However, if the developer believes that checked exceptions encourage error recovery and the creation of robust code, they would prefer Java. If a developer working in Java finds it infuriating to use try/catch blocks in the code then they may find Kotlin much better. Therefore, there is no need to catch or declare any exceptions.
