How to split string Arraylist Hashmap?

Question

I get a string which looks like this

["{action= some text, task= some text}", "{action= some text 2, task= some text 2 }" ]

how do I extract the content of action and task and store it in two seperate string? (E.g String action and String task)

nope. the value above is what I get from getting the string saved in arraylist hashmap. I wanted to extract the string, but I couldn't come up with a correct code :( — user3325919, Mar 02 '14 at 08:18
I tried to parse it as jason array, but the values are invalid. — user3325919, Mar 02 '14 at 08:23
it should look like `[{"action":"sometask"` and post your code. If its a string you can use split by `=` or use regex to extract the content. make sure whether its a json or not — Raghunandan, Mar 02 '14 at 08:26
That's not JSON. It's the string representation of a java `Map` object inside a java `ArrayList` object - and there's no easy way to parse that string without lots of `.substring()` statements or a complicated regex pattern. — Justin Jasmann, Mar 02 '14 at 08:31
Manually is the only way. Iterate through the characters looking for delimiters, choose the substring after that index to the next index, etc. Or a complicated regex pattern. I can't do it for you though. — Justin Jasmann, Mar 02 '14 at 08:35

If you are the Creator of this input String, I don't ever recommend this way of storing data. JSON is the best solution for you. No need to generate a complex REGEX that for sure will not be generic enough to accept your future edits

JSON is the enhanced way of storing files in a way of Parameter, Value data. You can simply create a JSON object and use its simple way of adding data data e.g. objectJSON.put("key", "value"). It is very similar to Object oriented, but with an external feature that is exporting your JSON object as a string file

Here is a good example of how to use JSON and parse them.
