How to correctly close resources?

I have methods that all propagate exceptions and then I have handling on one place, however I realized something.

Let's say I have method like this

public void foo() throws Exception e {
  Statement stmt = createStatement();
  doSomething(st开发者_如何学Pythonmt);
  stmt.close();
}

My issue is that if exception is thrown by doSometing() method the statement will not be closed, but I don't want to handle exception there. Is the right approach to have try and catch that only rethrows exception and finally to close statement?

public void foo() throws Exception e {

  Statement stmt = null ; 
  try {
    stmt = createStatement();
    doSomething(stmt);
  } finally {
    if(stmt != null) 
      stmt.close();
  }
}

Close it in finally block. All resources opened should be released/closed.

Modification to nos answer. You actually may initialize stmt before try block. That way there is no need to see if it's null, so this just suffice:

public void foo() throws Exception e {

  final Statement stmt = createStatemnt( );

  try {
    doSomething(stmt);
  } finally {
    stmt.close();
  }
}

Yes, you can throw the exception further

try {
   stmt = createStatement();
   doSomething(stmt);
}
 catch (Exception e) {
    throw e;
}
finally {
   if(stmt != null) 
      stmt.close();
}
