language-agnostic - 尝试/捕获并返回

Question

你更喜欢什么解决方案？我更喜欢解决方案2，但我想知道是否存在更好的做法谢谢大家

解决方案 1 - try/catch 嵌套

try
{
   //some code that could throws Exception1
   try
   {
        //some code that could throws Exception2
        return success;
   }      
   catch (Exception2 e)
   {
      return failure;
   }
}
catch (Exception1 e)
{
  return failure;
}    

解决方案 2 - 尝试/捕获顺序

try
{
   //some code that could throws Exception1 
}
catch (Exception1 e)
{
  return failure;
}

try
{
    //some code that could throws Exception2
}      
catch (Exception2 e)
{
  return failure;
}

return success;

Answer 1

-4！我认为这是一个合理的问题，尤其是对于刚起步的人。为什么这是一个糟糕的问题？

我个人会使用下面的代码，除非有令人信服的理由不这样做。

try
{
   //some code that could throws Exception1 
   //some code that could throws Exception2
   //some code that could throws Exception3
}
catch (Exception e)
{
  return failure;
}

Answer 2

你可以试试

try
{
   //some code that could throws Exception1 
   //some code that could throws Exception2
}
catch (Exception1 e)
{
   return failure;
}
catch (Exception2 e)
{
   return failure;
}

return success;
