[Q] Who is experienced in Java and has spare time? - Xperia Play General

Alright so I want to get started with Java programming, I have some basic knowledge of C++, Is there any person here who is experienced and is will willing to get me started with the basics?
All I want you to show me are the basics of Java, as in Syntax of the program, how to compile it and syntax of basic commands such as loops.

I've been transitioning over to Java recently after a long break from programming, I can tell you theres a hundred books on Amazon for under $20 that can show you all this stuff. The "For Dummies" books are great. Once you know some Java you can transition into Android, they have "For Dummies" for that too.

Alright thanks!

Where to start with android devving?

I am very interested in beginning to develope for android.. I just simply do not know where to start. (I am only 15..)
http://www.vogella.de/articles/Android/article.html or google "android tutorial"
Android's own guides are pretty good
http://developer.android.com/resources/tutorials/hello-world.html
(This assumes that you already know how to program in Java)
If you've got c++ background, google the Android NDK - that lets you sidestep the Java and work in c++ instead
If you know any C++ like programming language (this includes Java, php and similar), then simply follow the Android Developer Resources.
If you have no programming knowledge, you can either learn Java, or try the AppInventor: http://appinventor.googlelabs.com/about/

[Q] Need to learn java

Hiya,
I have noooooo knowledge about any computer language and want to learn Java as i heard that its the language required to develop android apps.

Thanks

That's a download for Java tutorials. To actually do them you'll need a compiler. I use jGrasp but there are many others you can use. Eclipse is pretty popular and they all do the same thing basically. A compiler can be downloaded on the internet, and you'll need to download Java from Sun Microsystems as well. Just to let you know you gotta be pretty dedicated, it takes a lot of time to make good apps. Google's App inventor is an alternative to learning code.
thanks for da help but da prob is dat i need to start from basics, like the full basics of programming even simple definitions, can u also guide me a book or ebook for that too so that i can learn the super basics like definitions first b4 learnin java
thanks
n btw the link doesnt work
This may get you started:
http://download.oracle.com/javase/tutorial/
But if you're never programmed in any language, you need to take an intro to programming course.

can u learn this intro to programming online? or thru any book?
I don't have anything I can recommend. But there's tons of info online. Just do a google search for 'Intro to programming'. That's how I found this:

thanksss ill take a look at it
I started with the book, hello android 3rd edition. Its a great book.
Nookie Froyo 0.6.8 (zoom2)/Tapatalk Pro
Did u start from zero from this book? I mean u had to learn the basic terms and definitions even??

You cant try this Stanford University lectures on youtube: http://www.youtube.com/user/StanfordUniversity#g/c/84A56BC7F4A1F852 ..or just search for "Mehran Sahami Programming Methodology" in itunes U if you use itunes.. Same lectures. I think its a really good starting point.
Bro you should check out "Starting out with Java: From control structures to objects" by tony gadis. Just google it. Its the one I used in my intro to programming course. It starts out as basic as can be. Its really good

I was in his shoes...about 15 years ago LOL Wow, where does the time go? 2 degrees and a couple careers later I guess.
What I would stress are a few things:
1. Learn how to do some flow charts before you write code
2. Learn the basics of program flow (if/else, do/while, switch/case statements)
3. Learn the "types" of your language (int, String, float, char, modulus etc.)
4. Learn some data structures (arrays, Lists, Vectors etc.)
5. Learn about functions and/or classes. Remember that a function should be fairly short and very specific to a task, like: getUserName, calculateCheckingBalance etc.
6. START SMALL AND WORK TO LEARN SOMETHING NEW EVERYDAY!
I can't stress how important #6 is. Do a "Hello World" program just to get used to writing some code.
Think of some simple programs like: write numbers 1 to 10 to an array and print them out backwards, ask user to input what year they were born in and print them back their age. Advance up to something like a ATM simulator where you can make deposits, withdrawals, check your balance. I did all similar type things in Programming 101.
I still love the Dietel and Dietel books...get one for JAVA and it's money well spent in my opinion.
I've uploaded some of my university lectures which start from the absolute basics.

[Q] Need some advice on Android apps

I want to start making apps. The only programing ive ever done was some visual basic and html back in high school and im not sure i remember much of that. I know that android uses java so my question is should i learn java first and then learn how to use it on android or just start by trying to make simple apps. Im planning on buying a few books so give me a head up if you know something that would help me out.
Thanks for any help in advance.
You should learn java first because if android apps are based from java, you will need to get the right coding information from java. Also android needs some high quality games so if I were you, i would learn java first so I can be able to meet these needs instead of making simple apps. We really need more developers like you who are willing to do this.

Developing for Android

I have no programming experience but I'm extremely interested in teaching myself how to program. My main goal is to one day develop my own apps for Android. Now I've read a lot online and most people recommend starting with Python as your first language as its easier to grasp than others. This sounds like a great idea but I dont believe you can code for Android in Python, correct?
So my question is, should I start with Python, get familiar with the language building my programming knowledge and later learn Java for Android? Or should I just jump head first into Java as my first language even though it may be more difficult to start with?
Thanks!!

Python is a great start.
However, with a good book like the "Head's first Java" you will also be able to start with (the desktop) Java. Get some programming knowledge before starting with programming for Android.

I looked at the book as an option for me but it says directly on the "Head First" website that these books assume you have expirence in other languages so I dont think that book is for me quite yet.
If I decide to go the Python route, I was looking at this book: http://www.amazon.com/Python-Progra...ie=UTF8&qid=1368992505&sr=8-6&keywords=python. Any thoughts on this book?

Android app development help?

Hello, I am a computer science student and i need some help getting into android programming, i know a bit, but frankly it aint much.
I know C++, C#,Visual Basic,(I know C++ the most) and i am currently taking a class on Java, but I want to get into android programming too!(I made a game for android a while back using unity.)
I don't need a tutorial from the ground up.
I know how setup the environment, sdk, run, etc.
I want to learn how to work with layouts and make them look cool,
basic app functionality, work my way to internet connected apps, databases, apps with root, gestures, all that fun stuff.
I am just wondering if anyone would share any info or site that helped them.
I am not that much of a noob to programming but i am to the android sdk and a rookie with java.
if any mentor would step up or something i would really appreciate it.
Thank you.
btw if you're feeling bored check out my game!

Yes, i know its hard, i have a better version, i just haven't compiled and uploaded, i will soon.
I think best Website is always developer.android.com.
It hasn't only the API reference, but also Training section and much more.
Whenever I don't know sth I first visit this.
Regards
According to me you should go step wise step...Watch video tutorials on YT.
You can ping me for help.
Thanks
then go to java website and start learning java. Loads of tutorial stuff is on their website
java.com
then go and download the Android SDK in about 2-3 months when you've completed the above.
