Hi i have a string which i get after converting a Map<String, Object> to a string by calling a toString method on the map.
Now i want to reconstruct the Map<String,String> by the String which i created earlier. How can i do it with regularexpression ? please help the patter will look like {Hello2=hi2, hello1=hi1}

Therefore, I, for one, will not even consider helping you. Maybe somebody else will, maybe not. Good luck.

Now let me ask a simple question first: Why did you discard that Map in the first place if you needed to use it again?

Because he wants a different Map. One is String, Object and the new one is String, String
Maybe.
... and if all the objects can be losslessly and unambiguously converted to Strings and back, which requires that they contain no binary data, which cuts out 99% of the useful data formats in the world ... and as long as you don't mind the parsing and space overheads ...
Java does already contain Serialization and XML for this kind of thing.
And there is no evidence the OP is round-tripping through a file. Maybe he is just tripping ...
I would keep hold of the original Map myself and wreak some magic on it.
