    }

Returns formatted string from given string and argument list

public static String getFormatString(String rscBundleName, String msgKey, Object[] args) {
        String formatStr = getString(rscBundleName, msgKey);
        
        return getFormatString(formatStr, args);
    }
    

getsFormatted string

  public static String getFormatString(String rscBundleName, String msgKey, Object arg) {
        
        if (arg == null) {
            arg = "NULL";
        }
        Object[] args = {arg};
        return getFormatString(rscBundleName, msgKey, args);
    }

Gets formatted string with one argument

   public static String getString(String rscBundleName, String msgKey) {
        ResourceBundle resourceBundle = (ResourceBundle)rscBundlesTable.get(rscBundleName);
        
        if (resourceBundle == null) {

            }
            
            // Cache resource bundle
            rscBundlesTable.put(rscBundleName, resourceBundle);
        }
        String str;
        try {

        }
        return (str == null) ? msgKey : str;
