Here, themultiCatch()function has two arguments. The first one is avararg, containing the types of “multiple exceptions.” A function will be executed if any exception in the definedexceptionsoccurs.This function is the second argument:thenDo(). As we can see in the code above, we wrap ...
In this code we only catch exceptions of type CustomException. 代码语言:javascript 代码运行次数:0 运行 AI代码解释 try { // code } catch (e: Exception) { // handling all exceptions } If you want to catch all exceptions you can use the catch with the argument of type Exception, which ...
The finally blocks is optional. It’s generally used to release any resources that were used in the try-catch. Typically a try can have multiple catches. Only the first matching catch would be run. Hence it’s recommended to stack the catches in the order: Specific Exception to General Exc...
A try block can have multiple catch blocks. When we are not sure what all exceptions can occur inside the try block then it is always a good idea to have multiple catch blocks for the potential exceptions and in the last catch block have the parent exception class to handle the remaining ...

Do not catch the base class Exception, use the most specific exception class you can. Create custom exceptions for uncommon cases to differentiate them. When handling exceptions, place the code that should be executed whether an exception occurs or not in the finally block. All exceptions in Ko...
Kotlin 是一种编译型的静态类型语言,这可能会给习惯于解释型、动态类型的 Python 用户带来一些初始障碍。本文档旨在解释 Kotlin 的大部分语法、概念以及与 Python 中相应概念的比较。 Kotlin 可以为多个不同平台编译。在本文档中,假定目标平台是 Java 虚拟机,它提供了一些附加功能——尤其是会将代码编译为 Java 字节...
Consequently, testing how a flow behaves when encountering exceptions allows us to ensure proper error handling. Let’s consider a flow that throws an exception after emitting a value: fun errorFlow(): Flow<Int> = flow { emit(1) emit(2) throw Exception("Test Exception") }.catch{e -> ...
十二、流异常(Flow exceptions) 当发射器或运算符内部的代码引发异常时,流收集器可以结束运行,但会出现异常。有几种方法可以处理这些异常12.1、收集器 try 与 catch(Collector try and catch) 收集器可以使用 kotlin 的 try/catch 代码块来处理异常
2. Unchecked exceptions do not need to be added as part of method signature and they are checked at the runtime, for example NullPointerException. Note: In Kotlin all exceptions are unchecked. Handling of exception in Kotlin is same asJava. We use try, catch and finally block to handle ...
