Answer 5

I choose try/catch when I am not shure what exactly will happen. For example everything outside my program like user input, load/save files, connection to database or a server....

You can always read the docomentation (java doc or whatever libary u r using) to check what exceptions can occure.

Answer 13

You use try when something may go wrong later, for example, using a audio file from external source, like this :

https://code.sololearn.com/Wl23AIEG6SuZ/?ref=app

Because the website may break down, or they remove the mp3 files. We use try-catch when loading the audio, and don't forget to use try-catch when trying the audio too (line 114 and 123).

throw is similar to assertion, for example, a program only for 18 years old or above, and the user entered that his age is 16, now you can use throw to raise an error to terminate the program and give the user a warning.

Answer 14

Many thanks for explanations 😊

Answer 15

Use try/catch to handle existing exceptions.

And use throws to generate a new exception.

Answer 16

Nice!

Answer 17

Try catch is used when you want to catch and handle the exception.
Throws is used to propagate the exception to the caller of the method then the caller will handle that exception..
