Primitive Datatypes In Java Made Simple | Int, Long, Float, and Double - Java Tutorial Series Part 2

Have you ever wondered how to use a java int, or why there's both a java int and a java integer? Why are there two types of java integers? And how do doubles fit into that?

Well in this episode we try to cover a little bit, pun intended, of everything. I try to make Primitive Datatypes In Java simple. By the time this episode is over you should be great and floating point arithmetic in Java. You'll know how to add a double and an integer, or a short and a long.

You'll even understand what some of these java errors mean, like this one: incompatible types possible lossy conversion from float to int
which basically means that you are trying to store a bigger type of number into a smaller type of number!
