What is exception handling in apex ?
Dilip_VDilip_V
Exception:
An exception is a special condition that changes the normal flow of program execution.
Causes:
Your code expects a value from something that is currently null
An insert or update statement fails to pass a custom validation rule you have set
Assigning a query that returns no records or more than one record to a singleton sObject variable
Accessing a list index that is out of bounds
Syntax: 
try{
     //Your code here
} catch (ListException e) {
     //Optional catch of a specific exception type
     //Specific exception handling code here
} catch (Exception e) {
     //Generic exception handling code here
} finally {
     //optional finally block
     //code to run whether there is an exception or not
}
