Concept explainers
a.
Try and catch block:
Java virtual machine (JVM) searches to handle the error in catch clause at that time of exception in code. So use try-catch statement to handle the exception in a code.
The following are the main keywords used in exception handling:
- Try
- Catch
Try block:
Try block contains the block of statements to monitor the exception and it thrown the exception
Catch block:
Catch block catch exception thrown by the try block to handle it.
General form for finally block:
// class definition
class class_name
{
//...
// Try block
try
{
// Try block statement
}
// Catch block
catch(Excep1 exObj)
{
// Catch block statement
}
// Catch block
catch(Excep2 exObj)
{
// Catch block statement
}
//...
}
Given code:
//Try block
try
{
statement1;
statement2;
statement3;
}
//Catch block
catch (Exception1 ex1)
{
}
//Catch block
catch (Exception2 ex2)
{
}
statement4;
