You are developing a feature to filter out invalid user inputs. Which conditional structures can be used to validate multiple conditions effectively and execute specific code blocks?

To validate multiple conditions effectively and execute specific code blocks for filtering out invalid user inputs, you would typically use if...else if...else statements. These conditional structures allow you to check various conditions and perform different actions based on the outcome. The switch statement is more suitable for situations with a single value and multiple cases, and try...catch is primarily used for error handling. A while loop is not a conditional structure for validation but a looping mechanism.
