What is the difference between exception handling in different programming languages?

Exception handling in different programming languages shares common principles but differs in syntax and implementation details.

In Java, exceptions are divided into checked and unchecked. Checked exceptions must be either handled within a try-catch block or declared in the method signature with throws. This forces the programmer to explicitly consider possible errors.

In other languages, such as C# or Python, there is no such division — all exceptions are considered unchecked, and handling them is not mandatory.

The syntax also varies:

• Java:

  try {
      // code
  } catch (IOException e) {
      // handling
  } finally {
      // cleanup
  }
  

• Python:

  try:
      # code
  except IOError as e:
      # handling
  finally:
      # cleanup
  

Additionally, some languages have constructs for multiple catch blocks for different exception types, while others do not. Overall, these differences are related to the language's philosophy and error handling requirements.
