I am currently writing a program in Java that uses a query populated jcombobox. I was wondering if there is a way to have a default selected value when the program executes. My query is a list of languages listed alphabetically, but I am curious if it is posible to have English (which is in the middle of the list) be the default value.
I know that when you manually hard code the values into the jcombobox you can set the default variable as
jcombobox.setSelectedIndex(int anIndex);
or
jcombobox.setSelectedItem(Object anObject);
but I am unsure when a ResultSet loops and populates the jcombobox.
Currently my code is:
languageLabel =new JLabel("Languages:");
rowFour.add(languageLabel,BorderLayout.WEST);//adding to my current panel
langbox = new JComboBox();
rowFour.add(langbox,BorderLayout.WEST);
try
{
con = DriverManager.getConnection ("jdbc:oracle:thin:@localHost:portNumber:ORCL", "username", "password");
statement = con.createStatement();
}
catch(SQLException sqle)
{
System.out.println(sqle);
}
langbox.removeAllItems();
langbox.addItem("Please Select...");
try
{
ResultSet rs = statement.executeQuery("select language from language order by 1");
while (rs.next())
{
langbox.addItem(rs.getString(1));
//Thinking that this is where a default value would be located
}
}
catch(Exception e)
{
System.err.println(e);
}
Thank you for your time.
