Are try-catch statements Bad?

Try/Catch isn’t a bad paradigm. It’s useful for situations where you can’t anticipate how certain errors might happen. No. It is even worse practice to do the error checks before executing the code because it means that you know something about how the implementation of a method works.

Should I use try-catch or throws?

From what I’ve read myself, the throws should be used when the caller has broken their end of the contract (passed object) and the try-catch should be used when an exception takes place during an operation that is being carried out inside the method.

1. First, the code in try {…} is executed.

What happens if catch block throws exception?
