I want to use final for my static variables. I now do for example:
	private static final Connection conn;
	private static final Combo      container;

and
	static {
		Connection tempConn;
		Statement  tempStmt;
		try {
			Class.forName("org.h2.Driver");
			tempConn = DriverManager.getConnection(
					"jdbc:h2:tcp://localhost/~/databases/stock", "sa", "");
			tempStmt = tempConn.createStatement();
		} catch (Exception e) {
			tempConn = null;
			tempStmt = null;
		}
		conn = tempConn;
		stmt = tempStmt;

and
		if (conn == null) {
			throw new Exception("Could not initialise");
		}

The only problem I have is with my array of String.
I now have:
	private static final String[] titles = {
		"Stock",
		"Number",
		"Dare",
		"Container"
	};

Because when I put it in the static block I get an error.
Beside this I can execute a statement like:
		titles[0] = "changed";

Can I get the initialisation in the static part? And in such a way
that the elements can not be changed?
