Hi <your name>,
Programming is about problem solving and expressing solutions. There are numerous tools you can use to program and Java is just one of them.
If you want to become a good Java programmer, you have to become a good programmer first. Switching from Java to C#, or even Visual Basic is like moving from a Toyota Corolla to a Honda Civic, or to a Ford Expedition. Of course, you may need some adjustment initially but if you have the fundamentals, you will have no problem driving.
A programmer’s basic building material is human intellect and your primary tool is you. Not your compiler or your GUI builder. Exercise your brain by solving problems without even touching a keyboard. Do not think about Java. Think about the solution. Write it plain English and ask a co-worker to review your solution.
Focus on improving your programming skills. Start with Steve McConnell’s Code Complete. If you want to learn programming, learn it the right way. At your stage, you still have a choice between programming in a good way or in a bad way. The choice you make early on will greatly influence your programming life as these choices become a habit then almost instinct. Bill Gates once said that any programmer who will ever be good is good in the first few years. After that, whether a programmer is good or not is cast in concrete. Do not be surprised if you meet a “certified Java programmer with 5 years solid experience, a CS gradudate taking a Masters” who still writes lousy code. I have met people who have the bad habit of running a program just to see if it works without even understanding every line they have written. Do not be like them.
Smart people love working with smart people. Find one in your company (this could be tough) and seek his/her advices. Read his/her code.
Do not aim for a certification yet. It is the classic college scenario where you study just to pass and not to learn. Learn first. The code you have written and the application you have developed are still the best measure of your skill.
Since you have already chosen Java as your programming language, just get a copy of Bruce Eckel’s Thinking in Java (TIJ). There you can find almost everything you need in your daily Java life. (For the rest, there is Google). It is free at www.mindview.net I usually do not recommend training schools because often, they just read and repeat what is already written in books. But if you know the lecturer is worth the money, go for it. But in training schools, you rarely know the lecturer. If you have access to computers 24×7, just get hold of TIJ.
And buy Code Complete and understand everything. If you cannot find one here, buy from Amazon immediately.
Good luck on your journey.
