An exception is a problem that arises during the execution of a program. An exception can occur for many different reasons. Some of these exceptions are caused by user error, others by programmer error, and others by physical resources that have failed i
The program includes two classes: Empty_File_Check and EmptyFileException. The Empty_File_Check class contains the main method, which serves as the program's entry point. In the main method, we call the checkFileNotEmpty method, passing the file name "test1.txt" as an argument. We handl...
In the process of writing a program, various exceptions may occur in the program at any time,so how can we handle various exceptions gracefully? 2. Demand 1. Intercept some exceptions in the system and return custom responses. for example: An exception occurs in the systemHttpRequestMethodNotS...
If an exception occurs in a method, the process of creating the exception object and handing it over to the runtime environment is called“throwing the exception”. The normal flow of the program halts and theJava Runtime Environment (JRE)tries to find the handler for the exception. Exceptio...
When wethrowan exception, the flow of the program moves from thetryblock to thecatchblock. Example: Exception handling using Java throw classMain{publicstaticvoiddivideByZero(){// throw an exceptionthrownewArithmeticException("Trying to divide by 0"); ...

Before proceeding with this post, I highly recommend you to check out my post on Introduction to Exceptions in Java. Introduction to try, catch and finally : The exception handling in Java makes use of try-catch-finally block which looks structurally somewhat like the one mentioned below. try...
That’s all I have in my mind for now related to Java exception handling best practices. If you found anything missing or you do not relate to my view on any point, drop me a comment. I will be happy to discuss this. 4. Conclusion ...
Exception handling is a very important yet often neglected aspect of writing robust software. When an error occurs in a Java program it usually results in an exception being thrown. How you throw, catch and handle these exception matters. There are several different ways to do so. Not all ar...
Without handling this exception, an otherwise healthy program may stop running altogether!We need to make sure that our code has a plan for when things go wrong. Also note one more benefit here to exceptions, and that is the stack trace itself. Because of this stack trace, we can often ...
