java - Is there an object like a "Set" that can contain only unique string values, but also contain a count on the number of occurrences of the string value? -
There is an object like "set" in Java that can contain only unique string values, but it also includes a count Is the number of string value in number?
This idea is simple.
A data set, ALA ...

I will set the text of each line set- I want to add to the object every time a non-unique text is added to the set, I also want to show a numeric value associated with the set to show how often it was added. So if I run it on the above data then set output will be something like this:
A: 1B: 2C: 3
Any ideas?
Maps & lt; String, integer & gt;
add public null (strings) {if (map.containsKey (s)) {map.put (s, map.get (s) + 1); } And {map.put (S, 1); }}
