0098 Exception Handling
<![CDATA[
An exception is a run-time error.
Java exception handling is managed via five keywords: try, catch, throw, throws, and finally.
Program statements that might have exceptions are contained within a try block. The exception handler is coded using catch statement
To manually throw an exception, use the keyword throw. Any exception that is thrown out of a method must be specified by a throws clause.
Any code that would be executed regardless after a try block is put in a finally block.
This is the general form of an exception-handling block:
try {
// block of code to monitor for errors
}
catch (ExceptionType1 exOb) {
// exception handler for ExceptionType1
}
catch (ExceptionType2 exOb) {
// exception handler for ExceptionType2
}
// ...
finally {
// block of code to be executed after try block ends
}
Here, ExceptionType is the type of exception that has occurred
