New to Java

I've managed to load the String for color out of the database.. like this

String sql = "SELECT * FROM flowchart WHERE ProcesID = " + ProcesID;
			System.out.println(sql);
			ResultSet resultset = statement.executeQuery(sql);
			
			while (resultset.next()){
				String tmpColor = resultset.getString("color");
				color = new Color(Integer.parseInt(removeChar(tmpColor, '#'), 16));
			}

which I found somewhere on the internet..
now I want to save stuff to the database.. which needs a varchar(10)
how do I get the correct value?
