Why not use try catch?
Try-catch is best used in parts of your code when you think mistakes will occur that are out of your control for whatever reason. 2. When Should You Avoid Using Try-Catch If you know an error is likely to happen, you shouldn't use the try-catch statement since you'd rather debug the problem than disguise it.In 'if-else' the conditions and the codes inside the blocks are got mixed, so that it becomes unreadable if there is many 'if-else' blocks. In 'try-catch' the codes to handle the exceptions and what exception to be handled, that are easily readable. In 'if-else', we have one else block corresponding to one if block.Although it might seem like a good idea to wrap all of your code in try-catch blocks to ensure that any exceptions are caught, this approach can actually harm your code. Overuse of try-catch blocks can lead to cluttered code and make it difficult to understand what's happening in your program.

Why not to use try-catch in javascript : ❌Don't Use Try-Catch For Input Validation

Or if you're expecting the user to have an age within a certain range, we also need input validation. We need to make sure the input the user provides is what we are expecting. Try-catch is not the tool to do that.

What is the alternative to try-catch

Is it bad practice to catch exception : If you need to add additional information, you should catch the exception and wrap it in a custom one. But make sure to follow best practice number 9. So, only catch an exception if you want to handle it. Otherwise, specify it in the method signature and let the caller take care of it.

The alternative to a try/catch is checking for the error before it can happen. Like If you're catching null-reference exceptions, you could instead add if(t!= null)'s. And that can be better since you can handle each specific instance, maybe even fixing it instead of quitting.

This answer will obviously vary from compiler to compiler and application to application, but generally yes — “try and catch” is slower than some of the other canonical alternatives to error handling.

Does try-catch reduce performance

In general, wrapping your Java code with try/catch blocks doesn't have a significant performance impact on your applications. Only when exceptions actually occur is there a negative performance impact, which is due to the lookup the JVM must perform to locate the proper handler for the exception.The alternative to a try/catch is checking for the error before it can happen.

Excessive try-catch blocks introduce a performance overhead. While this impact is often negligible, in performance-critical scenarios, it becomes crucial to minimize unnecessary try-catch constructs to maintain optimal execution speed. Indiscriminate use of try-catch can mask genuine issues within the code.

Why is it bad to catch exception in Java : Also when you catch all exceptions, you may get an exception that cannot deal with and prevent code that is upper in the stack to handle it properly. The general principal is to catch the most specific type you can. catch(Exception) is a bad practice because it catches all RuntimeException (unchecked exception) too.

When should you not catch exceptions :

Do not use try-catch unless you actually can handle specific exceptions.
If you need to catch general exceptions, always rethrow them.
If possible to handle errors without exceptions, do so only for perf critical code and only if profiling will show you exceptions are the top issue.

Does try catch affect performance

Excessive try-catch blocks introduce a performance overhead. While this impact is often negligible, in performance-critical scenarios, it becomes crucial to minimize unnecessary try-catch constructs to maintain optimal execution speed. Indiscriminate use of try-catch can mask genuine issues within the code.

How expensive is the try-catch block in Java in terms of performance Entering a try block and executing the code within it is not expensive as long there is no Exception. Creating and throwing Exception in Java is relatively more expensive due to the requirement of filling stack trace and possible stack unwinding.They also found that sometimes for correct handling of exceptions you need to nest Try-Catch-Finally blocks, however developers avoid doing so as it affects readability of the code. In this article, we look at various examples of nested Try-Catch-Finally statements in Java and how and when to avoid them.

Is it good to use try catch in Java : The Exception handling of Try catch in Java ensures that the flow of the program doesn't break when the exception occurs during the running of program.
