how to do this ?? should i use array or vector..

[Roy]

hi,
i got a question on whether i should use array or vector.. i need to define an multidimensional array..
i.e. array[name][money][time]..
but i do not know the size of the array.. i was reading that i can use vector or arraylist.. but i do not know if vector is able to take in the information like the above.. pls help.. if u can provide me with the starting code on how to declare vector and how to add the elements into the vector/arraylist.. i will be veri grateful..

I would suggest that you stick with ArrayList.
Vector's methods are synchronized - thus there might
be a performance hit.

but how do i declare an arraylist with 3 different "headings".. for example, using array... i could do this
array[name][address][telephone]..
but for arraylist .. how do i define the arraylist to create the same functionalitiy as the array...
thanks..

Could you store this information (name, address, telephone) in
a class then place the class in the ArrayList?
public class PersonInfo {
private String name;
private String address;
private String telephone;
PersonInfo( String name, String address, String telephone) {
this.name = name;
this.address = address;
this.telephone = telephone;
}
}
:

:
ArrayList info = new ArrayList();
info.add( new PersonInfo("name","address","phone") );
