Java Map can't get boolean

Question

I have a Map like this:

Map<String, Boolean> settings = new HashMap<String, Boolean>();

if I create a new boolean like this:

boolean bool = settings.get("something");

with or without (boolean) Gradle says:

Cannot cast java.lang.Object to java.lang.boolean

(Well, this Object is a boolean) If I try to do parseBoolean(String) Compiler works fine, but if I execute, I get:

Cannot cast java.lang.Boolean to java.lang.String

So, what should I do, i know that the first is right and works for other people.

Edit: A little fault, Gradle says:

Object cannot be converted to boolean

Which means pretty much the same.

Answer 1

The method get will return Boolean (Object) which is wrapper over boolean (primitive). Hence you may need to apply cast.

Answer 2

Depending on your situation, maybe you don't need to store a boolean at all? Would it be enough to use a HashSet and add Strings only if their value is 'true'?

Then you could write:

boolean bool = settings.contains("something");
