Compiling Error
Title
Question
Please this line of code is giving me compiling error "languageOptions.addAll(ArrayList(fossVsLanguage.get(selectedFoss)))".

This is the compiler error below:
<span style="background-color: rgb(250, 250, 250);">Type inference failed. Please try to specify type arguments explicitly. Type mismatch: inferred type is kotlin.collections.ArrayList<string>? /* = java.util.ArrayList<string>? */ but (MutableCollection<out string!="">..Collection<string!>) was expected</string!></out></string></string> </span>
<span style="background-color: rgb(250, 250, 250);">
</span>
<span style="background-color: rgb(250, 250, 250);">Please I restart it but the problem persist.</span>
<span style="background-color: rgb(250, 250, 250);">I also read the blog you send but the problem keep on coming.</span>
<span style="background-color: rgb(250, 250, 250);">Thank you.</span>
