What is exception handling in web technology?
In programming, exception handling is a process or method used for handling the abnormal statements in the code and executing them. It also enables to handle the flow control of the code/program. For handling the code, various handlers are used that process the exception and execute the code.
What is the importance of exception handling?
Why handle Java exceptions? Java exception handling is important because it helps maintain the normal, desired flow of the program even when unexpected events occur. If Java exceptions are not handled, programs may crash or requests may fail.
What is Exception Handling How can we use it in a program?
Exception handling ensures that the flow of the program doesn’t break when an exception occurs. For example, if a program has bunch of statements and an exception occurs mid way after executing certain statements then the statements after the exception will not execute and the program will terminate abruptly.
How the exception is handled using JavaScript?

What are the advantages of using exception handling mechanism in a program in C++?
the benefits of exception handling are as follows, (a) Exception handling can control run tune errors that occur in the program. (b) It can avoid abnormal termination of the program and also shows the behavior of program to users. (d) It can separate the error handling code and normal code by using try-catch block.
What is simulator in embedded systems?
Simulator is a tool used for simulation of an embedded system. Code tested for microcontroller unit by simulating code on the host computer. Simulator is used for model the behavior of the complete microcontroller in software. Functions of simulators: It monitors the response of system and determines the throughput.
