Currently have this implementation:
static Map s_AvailableGameTables = Collections.synchronizedMap(new TreeMap<Integer,Table>());
How开发者_StackOverflow社区 can I iterate over all it's content from the start to the end like an array?
Thanks
Assuming the declaration is
static Map<Integer,Table> s_AvailableGameTables = Collections.synchronizedMap(new TreeMap<Integer,Table>());
(not just Map
)
The following will iterate over all key/value pairs:
for (Map.Entry<Integer,Table> e : s_AvailableGameTables.entrySet())
{
int key = e.getKey();
Table tbl = e.getValue();
}
If you want to iterate over the entries (key-value pairs in the map):
for (Map.Entry<Integer, Table> entry : s_AvailableGameTables.entrySet()) {
System.out.println("key = " + entry.getKey() + ", value = " + entry.getValue());
}
