About the finally block of the try catch.

Question

I know that finally block contains the code that will be executed in any condition of the try catch.
However, I think it is unneccessary, since the stack after the try catch stack will be executed any way.
Any one can help?
for example
try{
System.in.read();
catch(Exception e){}
finally
{ System.out.println("does this matter?");}and
try{
System.in.read();
catch(Exception e){}
System.out.println("does this matter?");

Answer 1

However, I think it is unneccessary, since the stackafter the try catch
stack will be executed any way.That does assume that you catch and handle the error
appropriately.
Of course this is valid as well, and demonstrates
when you would WANT a finally clause.
Connection con = null;
Statement stmt = null;
try{
con  = Database.getConnection();
stmt = con.createStatement("Select * from dual");
// maybe something throws an exception here?
finally{
if (stmt != null){
stmt.close();
if (con != null){
con.close();
The finally block here might throw a null pointer exception itself use
null!=stmt null!=stmt
