Can we have any code between try and finally blocks?
A try statement should have either catch block or finally block, it can have both blocks. We can’t write any code between try-catch-finally block.
Does finally block always follow try catch block?
2. Finally block is optional, as we have seen in previous tutorials that a try-catch block is sufficient for exception handling, however if you place a finally block then it will always run after the execution of try block.
What happens when a catch block is not given?
What happens if an exception is not caught? If an exception is not caught (with a catch block), the runtime system will abort the program (i.e. crash) and an exception message will print to the console.
When do you use nested try catch blocks?
In some cases a nested Try-Catch is unavoidable. For instance when the error recovery code itself can throw and exception. But in order to improve the readability of the code you can always extract the nested block into a method of its own. Check out this blog post for more examples on nested Try-Catch-Finally blocks.
How much code to put in try-catch block overflow?
You might as well try/catch the whole lot, or add throws SomeException to the method signature and let the calling method decide what went wrong. Also, don’t worry about squeezing too much inside a try/catch. You can always extract that code into another method.
How to use try catch blocks as logical operators?
I just discovered some lovely code in our companies app that uses Try-Catch blocks as logical operators. Meaning, “do some code, if that throws this error, do this code, but if that throws this err… Stack Exchange Network

The second you comment out the catch, the compiler knows that it will never reach beyond finally in any condition, thus the error.
