Can you describe the features of exception handling in Kotlin?

In Kotlin, exception handling is similar to Java, but there are some differences:

• Kotlin does not have checked exceptions, so the compiler does not require mandatory catching or declaring exceptions.
• Exception handling uses try-catch-finally blocks, just like in Java.
• You can use try as an expression, meaning the result of the try-catch block can be assigned to a variable.

Example:

val result = try {
    riskyOperation()
} catch (e: Exception) {
    println("Error: ${e.message}")
    null
}

• It is also possible to use the throw operator to throw exceptions.
• Kotlin supports creating custom exception classes by inheriting from Exception or RuntimeException.

Thus, Kotlin simplifies exception handling by removing the need to declare and handle checked exceptions.
