General country data is stored in a helper class, Nation . The InternationalizationWizard creates a collection
of nations when it is first instantiated.
Example 3.24 Nation.java
1. import java.text.NumberFormat;
2. public class Nation {
3. private char symbol;
4. private String name;
5. private String dialingPrefix;
6. private String propertyFileName;
7. private NumberFormat numberFormat;
8.
9. public Nation(String newName, char newSymbol, String newDialingPrefix,
10. String newPropertyFileName, NumberFormat newNumberFormat) {
11. name = newName;
12. symbol = newSymbol;
13. dialingPrefix = newDialingPrefix;
14. propertyFileName = newPropertyFileName;
15. numberFormat = newNumberFormat;
16. }
17.
18. public String getName(){ return name; }
19. public char getSymbol(){ return symbol; }
20. public String getDialingPrefix(){ return dialingPrefix; }
21. public String getPropertyFileName(){ return propertyFileName; }
22. public NumberFormat getNumberFormat(){ return numberFormat; }
23.
24. public String toString(){ return name; }
25. }
