A typical user would say that the easiest display for Dates is 3 text fields
holding day, month and year (at least mine did...). So I think to achieve
this all you have to do is create a form JavaBean that gets dates in this
format ((int, int, int) | (int, String, int)) and uses a SimpleDateFormat
instance to parse these into a Date object that it offers via an accessor
method. Transformation can be done lazily or eagerly as long as the
validation happens in the right time.
something like this:
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
...
public void setOrderDay(int orderDay) { this.orderDay = orderDay; }
public int getOrderDay() {return this.orderDay; }
public void setOrderMonth(int orderMonth) { this.orderMonth =
orderMonth; }
public int getOrderMonth() {return this.orderMonth; }
public void setOrderYear(int orderYear) { this.orderYear = orderYear; }
public int getOrderYear() {return this.orderYear; }
public Date getOrderDate() {
Date result = null;
if(!(orderDay == 0 || orderMonth == 0 || orderYear == 0)) {
try {
result = dateFormat.parse(orderDay + "/" + orderMonth
+ "/" +
orderYear);
}
catch(ParseException pe) {pe.printStackTrace();}
}
return result;
}
public void setOrderDate(Date orderDate) {
String orderStr = dateFormat.format(orderDate);
StringTokenizer tokens = new StringTokenizer(orderStr, "/");
try {
orderDay = Integer.parseInt(tokens.nextToken());
orderMonth = Integer.parseInt(tokens.nextToken());
orderYear = Integer.parseInt(tokens.nextToken());
}
catch(NumberFormatException nfe) {
nfe.printStackTrace();
}
}
...
