I have a java map with string in its key and integer in its value. I want to remove a particular entry(key/value) from this map which doesn’t have value greater than 5. Can any body suggest me how can I do this?
Thanks!

If you’ve only got a regular map (i.e. no additional data structure that implements a reverse mapping), then your best option is to iterate the value set, test each value, and use
Iterator.remove()to remove the relevant ones.If you have a secondary data structure, you may be able to use it to identify the entries to be removed. But the “cost” is that such a data structure takes space to represent and time to update … and your code is more complex.
