Kotlin Exceptions Catching exception with try-catch-finally
Example
Catching exceptions in Kotlin looks very similar to Java
try {
doSomething()
}
catch(e: MyException) {
handle(e)
}
finally {
cleanup()
}
You can also catch multiple exceptions
try {
doSomething()
}
catch(e: FileSystemException) {
handle(e)
}
catch(e: NetworkException) {
handle(e)
}
catch(e: MemoryException) {
handle(e)
}
finally {
cleanup()
}
try is also an expression and may return value
val s: String? = try { getString() } catch (e: Exception) { null }
Kotlin doesn't have checked exceptions, so you don't have to catch any exceptions.
fun fileToString(file: File) : String {
//readAllBytes throws IOException, but we can omit catching it
fileContent = Files.readAllBytes(file)
return String(fileContent)
}
