Representing Whole Numbers in Java – Learn Java #4

[ad_1]
In this tutorial, we discuss the use of integers in the Java programming language for storing and manipulating whole numbers. We will also explore why floats and doubles, although capable of being set to “whole number” values – should not be used for storing whole numbers. The integer data type is ideal for whole number numerical data representation, and by the end of this video tutorial you should understand exactly why!

    These videos are great. I'm following along while also working through some text material (Learning Java, O'Reilly). It's nice to see how the videos and the text reinforce each other — great for learning.

    You forgot the octal number system.

    I love your structure, very quick short bursts of input for the viewer, to me thats smart, aids in longer retention, and like you said allows for the Java coder to quickly adopt new leanings immediately
