### Generic types with type parameters { #generic-types-with-type-parameters }

There are some data structures that can contain other values, like `dict`, `list`, `set` and `tuple`. And the internal values can have their own type too.

    public static final long PERSISTENT_TIMEOUT = 0;            // Infinite for persistent
