How to parse the string into map

Question

have a string like A=B&C=D&E=F, how to parse it into map?

Answer 1

I would use split

String text = "A=B&C=D&E=F";
Map map = new LinkedHashMap();
for(String keyValue : text.split(" *& *")) {
   String[] pairs = keyValue.split(" *= *", 2);
   map.put(pairs[0], pairs.length == 1 ? "" : pairs[1]);
}

EDIT allows for padded spaces and a value with an = or no value. e.g.

A = minus- & C=equals= & E==F
