Hello all I am using Ivor Hortons beginning java 7th addition and I am having a hec of a time understanding the the bit wise operators, casting, op operators use,shift operators, just the whole math section of chapter two past the basic math operators. Can anyone recommend some supplemental material so that i can understand these functions much better. He explains the functions gives examples and try out code that should put it together but I'm having trouble putting it together. At the end of chapter 2 there are four exercises and I believe I can only do 1. I really want to get my associates certs by oct. so I'm using Ivor's book to get a foundation and then start doing core java vol one and two for the rest, and then the study guide for the cert test. I would like to have my professionals certs by the end of the year but I must first make it through this part, s.os from a determined but struggling green horn thanks .

i thought i stated it was ivors book my apologies my hands seemed to move slower then my brain

are you saying the fonts have one 1bit and 31 0's ? and the & and | operator can be used to manipulate these bits?
im trying to get a firm grasp on the arithmetic operators

a better understanding of
floating point arithmetic
op= operators
and the cast and explicit cast any suggestions or explanations from the community would be grateful.

im trying to understand what ivor is saying about the and, and or operators and the mask.
if i understand it correctly the & operator prevents you from changing a bit that is one when a mask is involved and changes all others to 0
and the | operator forces a bit to 1 when the mask is 1.

my question is when would i need to actually use the & ,| operators ?when will i need to manipulate the bits in a variable?

thanks for all the great advice guys. I have looked at the HF book for Java but it dosent cover jdk7 that's why I got the other books for the jdk7 and beginner,intermediate and advanced coverage. I read the 10,000 hours article and understand the journey ahead of continual learning and embrace it fully. Right now I'm just striving for competency as I recall something i read stating knowing Java will make learning c++ and c# easier because of their similarities. Does anyone have any experience with the javaonline.org course?

thanks sheriff but I won't start school till September and to get the job in Memphis I need to know Java and at least 1 or 2 other languages can you suggest an order for the books I have listed that I should follow? Was thinking beginners Java with I or and follow that with learning or beginning Java then thinking in Java core Java 1&2 then effective Java and last code complete and Java ranch to ask a bunch of noob questions:-) I plan on committing 8-10 hours a day studying to grasp the concepts and get to an advanced level by the end of the year
