uint8_t foo = (uint8_t)69;

In theory, there should be no need to specify the type twice. The ideal circumstance is something like

    uint8_t foo = 69;

Until java 7 you had to write:

    List<String> list = new ArrayList<String>();

It feels silly to have to write the type parameter twice. But now you can say:

    List<String> list = new ArrayList<>();

It's usually not a huge deal, but occasionally the stutter can be more pronounced:

    Map<String, List<Map<Integer, Set<Float>>>> map = ...
