sql - Manage Exceptions in Java -

i'm doing small database program.

connection connection = drivermanager.getconnection(..., ..., ...);  string createtable= "create table employee ...";  try {     statement stmt = connection.createstatement ();     stmt.executeupdate(createtable);     stmt.close();     connection.close (); } catch(exception ex) {     system.out.println("erreur : " + ex.tostring()); }   

when run program going fine, second time exception :

duplicate table name : employee

ok fine know how manage exceptions, how managing every possible exception. :

if exception duplicattion error then display custom duplicate message.

if it's duplicate primary key then display error message , on.

thanks.

you'll have parse exceptions method string "subtype" of actual sql exception:

 try {    // ...  } catch (sqlexception e) {   if (e.getmessage().tolowerstring().contains("duplicate table name")) {    // handle duplicate table name problem   } else if ( /* ... */ ) {    // ...   }  }
