Why You Should Avoid Using Checked Exceptions in Java

The author of the text argues that Java's checked exceptions are a flawed design choice that causes unnecessary complexity and pollution in code. They claim that checked exceptions make it difficult for developers to handle errors explicitly and elegantly, leading to "leaky abstraction" problems where the compiler forces users to handle specific exceptions even when they may never be thrown. The author suggests that unchecked exceptions are more suitable for handling errors and that alternative approaches like monads can provide a more elegant solution. They also note that other programming languages like Kotlin and Scala do not have checked exceptions, and that some Java APIs, such as the `java.time` package, avoid using them altogether. The author concludes that the debate around exception handling is about when and where to handle errors, rather than the mechanisms used to accomplish this.
