finally java code example

Example 1: importance of finally over return statement

finally block is more important than return statement when both are present 
in a program. For example if there is any return statement present inside 
try or catch block , and finally block is also present first finally statement 
will be executed and then return statement will be considered.

Example 2: java program for try catch finally

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");
 }
}

Example 3: finally always after try catch

Finally block is ALWAYS executed AFTER try / catch Javascript blocks.

Example 4: importance of finally block in java

Finally block is used for cleaning up of resources such as closing connections, 
sockets etc. if try block executes with no exceptions then finally is called 
after try block without executing catch block. If there is exception thrown in 
try block finally block executes immediately after catch block.
If an exception is thrown,finally block will be executed even if 
the no catch block handles the exception.
