The fundamental difference between checked and unchecked exceptions is that the compiler checks checked exceptions. On the other hand, the compiler does not check unchecked exceptions. Another difference is that checked exceptions need to be unequivocally caught or replicated. Unchecked expectations do not have this parameter.
They don't have to be decreed thrown or caught. A checked exception is a subclass of exception and illustrates a function that generally reflects errors in a program's logic. It aims to allow for the smooth execution of the program at run time. If you don't handle the checked exception, then the compiler objects.
