Collect the result using the collect () method. 1=100 2=1020 3=300 5=500 after sorting 1=100 3=300 5=500 2=1020 sort a map<key, value> using sorted () method in java if you are working with streams, you can use. If we need to sort the hashmap by values, we should create a comparator.

The idea is to put all data of hashmap into an arraylist.then extract all the keys of hashmap into an arraylist.
