You do have to download Java for Minecraft. Think of it as Flash Player, you need Flash Player to watch videos and such. Java makes it so you can play Minecraft, on Mac, Java is already installed so you won't have to download Java anymore. But on windows PCs, you have to manually download Java and install it.
