I have 1 month to go before the semester starts, and I dont have any prior programming experience. The course is going to be based entirely on java programming, so I was hoping to be able to use this 1 month to learn something
What is the best way to start learning java programming?
there are MANY java programming tutorials online for free.
i highly suggest that you google "java tutorial"
and use as many as possible. I am in the same predicament as you, and i used the tutorials and now the summer semster has started. I know a lot more than the other students, and java isnt such a language that your head hurts by trying to understand it. Use those tutorials, and then if you want, go out and buy a book . I recommend the Schaum's series. that series is very easy to understand, and very thorough!
good luck with your java adventures!!!

I hope it will help. I learn HTML from that website.

Complete guide to learning java, straight from Sun's own servers.
Reply:1.The very main thing: be sure than you do not want to be a programmer.
2. Start to drag-and-drop with any Java tool :-)
Reply:Get Java for Dummies or a copy of Detail %26amp; Detail java programming, both will give you a jumpstart on the subject matter.... Good luck
Reply:You'd be better to use textPad, use the trial version, and Eclipse. As far as I know, most of java programmer build their application with Eclipse. But for the experimental purpose, textPad is easy to use. You can just press Ctrl+1 to compile, and next Ctrl+2 to run the program you've created. Others answers are correct, use the online tutorial and try to understand the basic structure of the java programming environment.
Next time you're deep into the java programming, you will find that it's too many jargon with java itself (e.g. Java, javascript, javabean, J#, Java Server Pages, Java Swing, J2SE, J2RE, etc.) Just try to understand what is the definition of each, and the differences.
One more thing, don't forget to drink Java Coffee when you're doing java programming. ^^. Good Luck!!

I want to pursue a career in Java programming, what can I expect?
Is the java programming business worth going into overall? Is it going to be long hours in front of a computer? Is the salary good? Would it be hard to find a job as a Java programmer? What sort of degree should I get?
Obviously I should get Java certified, but should I go for a bachelor degree in science as well?

Good for you for being interested in Java! It's an excellent language; not perfect, but a wonderful career choice (in my opinion).
I disagree with many aspects of the answer above. I'm a senior software engineer with 7 years of Java experience (and 20 years of programming prior to that). I have a B.S. in Computer Science. I switched to Java and have not regretted it.
The link below can give you an idea of the salary range, which depends on where you are, the size of the company, your experience, and other factors.
Java will be around for a long time. Heck, there is still a need for COBOL programmers, and that language was created in 1959! Java is similar enough to Microsoft's (evil) C# language that you could switch to that if you needed to. And once you know Java, switching to C/C++ would be pretty straightforward. Lots of options.
The offshoring problem mentioned in the answer above is a mixed bag. Yes, many programming jobs have gone overseas, but the tide may be starting to turn back. Many companies are realizing how hard it is to manage teams in a different country. Language, cultural and timezone differences make it more of a challenge than many companies realized at first. Additionally, some predict a shortage of programmers in future years since many parents are discouraging their kids from going into the field because of all the press about outsourcing.
It will be long hours in front of a computer. But you also get to work with others. The pay is usually very good. Start with a BS or BA degree, do an internship with a software company if you can, and then try to get hired. Open source community experience can be a big plus these days. Certification is nice but pretty optional from my perspective. Hardly any of my programming colleagues are Java certified, and it hasn't slowed their careers down. I haven't found a need for a Master's, but if it turns your crank, go for it.
I will agree that the broad education base of a degree is good - communications skills, teamwork, analysis and critical thinking, all are important today. If your school has a Mentoring program, hook up with a Software Engineer and ask to "job shadow" them for 1/2 day to see what it's really like.
Don't think that one language (or operating system) is all you'll ever need. I started with Pascal in the 80's, used C for 10+ years, then Java. Today you could try Perl and Visual Basic and others. Install unix on that old PC in your closet and learn Bourne shell scripting.
Best of luck with your career!
Reply:You shouldn't focus on being a java programmer. You should get a degree in Computer Information Systems from a respectable school (like a state university). A good university program in Computer Information Systems will provide you with a great overall understanding of the Computer Information Systems environment. They should teach you a couple of languages, database modeling, SQL, project management, systems analysis, requirements gathering, and great written and oral communication skills. These will all be necessary in your career. Above all, a good program will teach you how to learn. This is important because languages and specific technologies have relatively short lifespans. You could learn one language and it may be obsolete in 6 or 7 years. You need to learn how to pick up another language and be prepared to do so many times in your career. Also, you may get bored with programming and decide to become a requirements person or a project management. These shifts in your career will build upon what you have done in your past, but continue to advance your career.
The area of programming is kinda iffy right now. The trend is toward offshoring programming. Therefore, the price people are willing to pay for a java programmer is going downward. Many corporations have offshored all of the development. They retain IS project managers and architechts to help manage and direct development efforts occuring offshore. An offshore resource ir running around $20 or $30 an hour these days. Java programmers (contractors) used to get $120 an hour here. The availability of low cost offshore programmers has brought the cost of domestic programmers down. However, there will always be companies or organizations that don't go for offshoring and will want onsite resources.
My advice to you is to broaden your career objectives to a career is computer information systems and be open to learning other aspects of that career besides just programming.
Purdue University has a great program. I also know that Penn State has a good program.
I'm a Purdue Grad. I have 12+ years of experience in IS working at multiple Fortune 500 companies in multiple roles in IS.

Can you use a reg 9 volt battery instead of a 9 volt rechargable java battery for an electric paintball gun?
I have a spyder electra w/ a java 9v rechargable battery that's low on power but i don't have a charger for it. I have regular 9v batteries but i don't know if it's safe for the board.
Can you use a reg 9 volt battery instead of a 9 volt rechargable java battery for an electric paintball gun?
hi there
yes as long as the batterys are the same size and the connection plug is the same.
Reply:You can, but they don't last very long, and sometimes they will not work.
I had a problem with my old Spyder E-99Avant, the rechargable was fine, but it ran out druing a tournament, so I put in a regular 9V, and it only lasted a couple games. I tried another new 9V, and it didn't work at all.

How would i write a program in java?
That executes this
11+22+33+44 = 110
Mean = 110 / 4 = 27
1.2345+12.345+123.45+1234.5 = 1371.5295
Mean = 1371.5295 / 4 = 342.882375
My proffesor is really bad at teaching Java, and instead of teaching us the subject, he goes in the internet and finds some online book and gives it to us. He refuses to give the class help, he says "the awnsers to your problems are on the online book." he's lazy.
Well anyways, thanks.

The first line (Where you add all the numbers) is a postfix expression. To be bale to evaluate this esily, you'll need to convert it to an infix expression (this will also handle mathematical statements with brackets and multiplication/division/subtraction statements too).
You can find algorithms for it if you do a search. Find a pseudocode or actual code version of the algorithm and use it.
Reply:Try talking with one of the principals in the school and mention the problem you are having with the instructor (i.e. their lack of teaching). Ask if they would sit in on a class so they can see first hand the teaching style of the instructor.
As to the program, are you taking user input or are these values hard coded? Taking input would require a bit of extra work to use arrays where hard coding would take about 4 lines of code.
