Delete some keys-values from a HashMap

[Antonis Kaklis]

Hi to all,
I have a little problem. I use a map of type ConcurrentHashMap to store old filenames and renamed filenames
e.g. Map<String,String> renameMap =......
What i want is how could i delete some key-values in my map(based on some criteria)?Not all.

Thanks in advance

If you don't have the key strings that you want to remove, you can obtain an iterator() from the Map and remove mappings selectively as you iterate through all mappings.

Through its entrySet() method yes. Map doesn't have an iterator() method itself (although maybe it should have...).
