try and finally in java

Explain try & catch finally block in Java

try block: code that is protected for any exceptions. and it is mandatory (only try)
catch block: if any exception happens during runtime in the try block, 
the catch block will catch that exception.
if any exception happens during runtime in the try block, 
control will be given to catch block.
An optional finally block gives us a chance to run the code which 
we want to execute EVERYTIME a try-catch block is completed 
– either with errors or without any error.

class JavaException { public static void main(String args[]) { int d = 0; int n = 20; try { int fraction = n / d; System.out.println("This line will not be Executed"); } catch (ArithmeticException e) { System.out.println("In the catch Block due to Exception = " + e); } System.out.println("End Of Main"); } }
