Android : Check a particular string and delete part of string in android

I have a string format stored in shared preference. I would like to check if a particular word exists. If yes, then delete those few words which start from x and ends at y.

Something like this: For example:

 String items = "Veggies=Beans-Carrot-Potato-Onions--DailyUse=Milk-Yogurt-Soap--Fruits=Apple-Banana-Grapes-Pears";

I would like to check if the above string items has "DailyUse=" if so delete all the words that are after "DailyUse=" until "--". So that my string looks like:

String Newitems = "Veggies=Beans-Carrot-Potato-Onions--Fruits=Apple-Banana-Grapes-Pears";

Is this possible? If so, how do I go about doing this?

Thanks!
