Question

Struts2中，下面一段代码中后面加了注释的那句是什么意思？

```
public Object convertValue(Map context, Object value, Class toType) {
if (toType == Locale.class ) {
System.out.println( " Converting String to Locale " );
String locale = ((String[]) value)[0];
return new Locale(locale.substring( 0 , 2 ), locale.substring( 3 )); //?
} else if (toType == String.class ) {
System.out.println( " Converting Locale to String " );
Locale locale = (Locale) value;
return locale.toString();
}
return null ;
}
```

Answer 1

转换Locale
既是切换语言，国际化程序设计 。
