How many exceptions are there?
There are three types of exception—the checked exception, the error and the runtime exception.
There are mainly two types of exceptions: checked and unchecked.
e.g. when compilation fails for some reason your method can only throw one exception. if you have to cover different opportunities you might declare you method to throw the parent class of all exceptions "Exception".
We can use try catch block to protect the code. Catch block is used to catch all types of exception. The keyword “catch” is used to catch exceptions.

Table 5.1 shows the seven different types of exception recognized by ARM processors.

By handling multiple exceptions, a program can respond to different exceptions without terminating it. In Python, try-except blocks can be used to catch and respond to one or multiple exceptions. In cases where a process raises more than one possible exception, they can all be handled using a single except clause.
How many keywords are in exception?
The exception handling fundamentals in Java revolve around the five keywords- try, catch, finally, throw, and throws. These keywords form the base of exception handling. All the exception handling mechanisms in Java are a result of these five keywords.
Common exception words are important because they are just that: common. They are words that appear frequently in texts and that help readers understand what they are reading. For example, 'the' is a common exception word taught in most programmes at the beginning of the Reception year.
- Predefined exceptions are error conditions that are defined by PL/SQL.
