Java Video Tutorial 3: Variables and Arithmatic (Part1)

whiteboy2k10 Says:

Apr 23, 2009 - Ugh! Vidoes like this annoy me on YouTube. If your gonna make a video please get your facts straight. A vairble does not store data it is a reference to data. Also, variables are not the core of a program. I have written many programs with no variable whatsoever, I just used value returning methods within algorithms

May 5, 2009 - Thank you, aphonik!!! Yes...the 8 primative data types, as seen in this video, store values DIRECTLY into memory. A reference variable, such as String stores a reference to that variable. See D.S. Malik 5th ed, Java Programming, page 120. There's even a picture.

Jun 8, 2009 - Nothing, but I think it would return an error because he used the name "myFloat" twice(as a float and a double) I'm not sure if that's aloud in Java. I don't know that much about it(hence watching this tutorial :3). It works in some languages and doesn't in some. But overall great tut.

Feb 15, 2010 - Thanks and great.. But you should probaby call the double variable "myDouble" instead of repeating "myFloat"

BabyLatina1010 Says:

Feb 17, 2010 - definitly agree. it wouldn't compile if he declares myFloat twice, should have made his double variable called myDouble. other than that, simple clean tutorial, great for beginners!

Jul 22, 2010 - Dude, you're so sweet ;) "Float can hold smaller numbers then double. Double can hold extremely big numbers, float can hold small numbers - OH - not smaller than - it still hold quite large numbers but not as large as double". Haha, love your videos!!

Nov 8, 2011 - You assigned myFloat twice?Even though they're two data types wouldn't it cause confusing if you called them for a argument?
