You need to perform different actions on each element of a heterogeneous list (i.e., containing different types of objects). How would you implement the loop to handle different types and perform type-specific actions?
- Use a custom iterator with type-specific handlers.
- Use a for-each loop with instanceof checks.
- Use a series of if statements to check each element's type.
- Use a switch statement inside a for loop.
To handle different types in a heterogeneous list, you can use a for-each loop and check each element's type using the instanceof operator. This approach allows you to perform type-specific actions. The other options may not be as flexible or efficient for this task.
