Re: Possible to create an array and call object constructors at the
same time?

Hi,
I'm using Java 1.6. I was wondering if there is a shorter way to do
this. I initialize my array and then loop through the array,
assigning a newly created element at each step ...
DatePref[] prefs = new DatePref[arraySize];
for (int i=0; i<prefs.length; i++) {
prefs[i] = new DatePref();
...
}
I was wondering if there was a more all-in-one solution for
initializing the array and automatically calling the constructor for
each object in the array.
DatePref[] prefs = {
new DatePref(),
new SubclassOfDatePref(),
new AnotherSubclassOfDatePref(),
new StillAnotherSubclassOfDatePref(),
};
Not an enormously practical construct, and no use at all
if arraySize isn't known at code-writing time. The choice of
initializers is meant to illustrate one problem with the idea;
"Others will occur to your thought."
It is fine if we change the rules to use
some type of Collection as opposed to an Object[] .
I'm not sure what you mean by this.
