How do I create a heterogeneous Array in Scala? -

-

in javascript, can do:

["a string", 10, {x : 1}, function() {}].push("another value");

what scala equivalent?

arrays in scala homogeneous. because scala statically typed language. if need pseudo-heterogeneous features, need use immutable data structure parametrized covariantly (most immutable data structures are). list canonical example there, vector option. can this:

vector("a string", 10, map("x" -> 1), ()=>()) + "another value"

the result of type vector[any]. not useful in terms of static typing, in there promised.

incidentally, "literal syntax" arrays in scala follows:

array(1, 2, 3, 4)     // => array[int] containing [1, 2, 3, 4]

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
