You should not use exceptions for control flow simply because it is bad design. It doesn’t make sense. Exceptions are for exceptional cases, not for normal flow. Performance probably won’t be an issue in this situation because for most modern applications on modern hardware, you could throw exceptions all day long and the user wouldn’t … Read more
String timeToConvert = “2018-06-25T08:06:52Z”; Instant inst = Instant.parse(timeToConvert); LocalTime time = inst.atZone(ZoneId.of(“Africa/Nairobi”)) .toLocalTime() .truncatedTo(ChronoUnit.MINUTES); System.out.println(“Time in Nairobi: ” + time); This prints: Time in Nairobi: 11:06 I am using java.time, in this case the backport to Java 6 and 7. This backport is available in an Android edition too, which you may use for low … Read more
Warnings and notices are not technically exceptions in PHP. To catch an exception it has to be explicitly thrown, and many of the built-in libraries of functions do not throw exceptions (mostly because they were written before PHP supported exceptions). It would have been nice if somehow exceptions were built on top of the existing … Read more
The EDT exception handler doesn’t use Thread.UncaughtExceptionHandler. Instead, it calls a method with the following signature: public void handle(Throwable thrown); Add that to MyExceptionHandler, and it should work. The “documentation” for this is found in EventDispatchThread, which is a package-private class in java.awt. Quoting from the javadoc for handleException() there: /** * Handles an exception … Read more
PERFORMANCE: There is absolutely no performance difference in where the try/catch structures are placed. Internally, they are implemented as a code-range table in a structure that is created when the method is called. While the method is executing, the try/catch structures are completely out of the picture unless a throw occurs, then the location of … Read more
Is it recommended to keep the lines inside the try catch to bare minimum? No. Can’t imagine how you could think that the length of a try block or indeed of any block can have any impact on performance. Does the code inside the try clause run slower or cause any performance hit?. No. As … Read more
There is no try catch statement in Rust. The closest approach is the ? operator. However, you do not have to create a function and a match statement to resolve it in the end. You can define a closure in your scope and use ? operator inside the closure. Then throws are held in the … Read more
I had the same problem and as it turned out, my system had no swap space enabled.

If any of the code in the try block can throw a checked exception, it has to appear in the throws clause of the method signature. If an unchecked exception is thrown, it’s bubbled out of the method. The finally block is always executed, whether an exception is thrown or not.
