Javadoc cannot see inside blocks of code.
You could document these using a doc comment:
/**
* Values are: Checking, Savings, Credit, Money Market
*/
private static String[] accountTypes = {
"Checking", "Savings", "Credit", "Money Market"
};
or if this class has a getter to get those values,
you could modify Javadoc to call that getter and
display the values.
