Converting string of an array back to array

Question

I have this string : "[ name = preload cacheHits = 0 onDiskHits = 0 inMemoryHits = 0 misses = 0 size = 0 averageGetTime = 0.0 evictionCount = 0 ]",

and want to convert it in array like [ name = preload cacheHits = 0 onDiskHits = 0 inMemoryHits = 0 misses = 0 size = 0 averageGetTime = 0.0 evictionCount = 0 ],

How can we do it?

ehm ... I don't see a valid array type there. a composite object, sure, but not an array, since they're different types. — Stultuske

It's not array. maybe a MAP is right for you? I see it's more suitable for an associative array — Amerousful

@skr have you debug and checked whether it's coming as array or string. if you will debug at response then for array you will get response=ArrayList<E> and for string it will give you response="[ name = preload cacheHits = 0 onDiskHits = 0 inMemoryHits = 0 misses = 0 size = 0 averageGetTime = 0.0 evictionCount = 0 ]" — Tanmay Naik

@TanmayNaik, I get the data in string form, I can not do much at the backend as well as the library that sends this info is sending it in string form. I have managed to convert it in Json using javascript. I was looking for a solution in Java. — skr

String response="[ name = preload cacheHits = 0 onDiskHits = 0 inMemoryHits = 0 misses = 0 size = 0 averageGetTime = 0.0 evictionCount = 0 ]";
String replace = response.replaceAll("^\\[|]$","");
System.out.println(Arrays.asList(replace));

I never thought I could easily do it using regex.
