What are some effective exception handling techniques in Ruby?

In Ruby, you can use begin, rescue, and ensure blocks for exception handling. Would you like examples?

Yes, please provide an example of using begin and rescue.

Sure! Here's a simple example:

begin
  # Code that might raise an exception
  result = 10 / 0
rescue ZeroDivisionError
  puts 'You cannot divide by zero!'
end

What about using ensure?

The ensure block runs regardless of whether an exception was raised. Here's an example:

begin
  # Code that might raise an exception
  file = File.open('example.txt')
rescue Errno::ENOENT
  puts 'File not found!'
ensure
  file.close if file
end
