What do you mean by multiple vectors?
I have a program that uses a hashtable that stores a vector as objects.
Think of this as categories and items.
If I have a grocery store. I might have categories of
"Canned Foods", "Vegetables", "Meats".
And items inside of them
I have vectors for all the items under one category
so my vector for Canned Foods will look something like:
Beans | Peaches | Corn
I have a hashtable to store these keyed by category name:
Hashtable:
Key Value
"Canned Food" Vector( Beans | Peaches | Corn )
"Vegetables" Vector( Spinach | Broccoli | Tomato )
"Meats" Vector( Chicken | Veal | Pork )
So my program would do something like: (Not complete and not tested)
private Hashtable myStore;
public void createStore()
{
//database code: not best way to do db code and not
complete!
rCategories = stmt.execute("select category_name from
categories");
while( rCategories.next() )
{
String category = rCategories.getString(1);
Vector vItems = new Vector();
//database code: not best way to do db code and not
complete!
rItems = stmt.execute(
"select item_name from items where
category_name='"+ category +"'");
while( rItems.next() )
{
vItems.add( rs.getString(1) );
}
myStore.put( category, vItems );
}
}
