    Angry Generics Wildcard array of references?

    An array of references to a specific generic type is not allowed in Java.
    e.g.,
    ArrSpec<String> arrs[] = new ArrSpec<String>[10];
    is not allowed though the type checkng and memory allocation can be done at the compile time itself.

    Instead of this, Java allows to use Wildcard type array of references to a generic type.
    e.g.,
    ArrSpec<?> arrs[] = new ArrSpec<?>[10];
    is allowed though the type checking, memory allocation and any type of values to be stored would be decided at the runtime.

    This above behavior is confusing and needs more clarification!

    Welcome to the forum! Please read this topic to learn how to post code in code or highlight tags and other useful info for new members.

    You appear to be quoting a Java reference. Please provide a link to the reference or a title plus version number if it is not available on the web.

    The best way to eliminate confusion is to write code.

    Good luck!
