I've been learning Java from docs.oracle... for a while now, but despite all the examples here and there, once the tutorial poses a question to me I'm always like -- how do I start? I can answer the theoretical questions very well... but the practical ones always make me feel like -- what do I first type into NetBeans IDE? Apart from programming I'm reading something else... and I'm pretty a naturally brilliant student, but seriously "real-life" coding ALWAYS puzzle me. I'm always left hanging somewhere within the code exercise.
Please you programming gurus that -- learnt coding ONLINE (by yourselves). How was it? As in -- I don't see it as hard but... how do I start? Or should I just learn the whole thing before even laying my hands on any real life code? Do I need to cram and memorise every syntax? Or should I just be referencing to the tutorial often. How long would it take me to be able to -- see a piece of code and quickly detect the error? Or is there any cheat to learning programming?

How can I ever thank you guys? You just did the BOMB!!!!!! I've been on it for like -- 20 hours... and within few minutes (with your help) I'm done!! Thanks guys!!

asalimpo:


you shouldnt create a new variable .
For windows 7 and earlier,
there,s a path variable under system properties.
Click it then copy the full path to the jdk compiler and paste it at the end of the value textfield,with other values there. End with a semi colon.

The path to the jdk should be
rootdrive: /program files/.../java/java-version/bin/

My current PATH is -- C:\WINDOWS\system32;C:\WINDOWS;C:\Program Files\Java\jdk1.8.0\bin
And I'd try what you suggested

I also tried this -- C:\Program Files (x86)\Java\jdk1.8.0_25\bin\javac HelloWorldApp.java

and this -- C:\Program Files (x86)\Java\jdk1.8.0\bin\javac HelloWorldApp.java

Also this -- C:\Files (x86)\Java\jdk1.8.0\bin\javac HelloWorldApp.java

And this -- C:\Program Files\Java\jdk1.8.0\bin\javac HelloWorldApp.java

I've also created a PATH is system for JDK1.8.0 as in -- C:\WINDOWS\system32;C:\WINDOWS;C:\Program Files\Java\jdk1.8.0\bin but the whole thing is still MESSED UP!


And please I'm still a beginner!!

Theorix:
Make sure u change directory to point to were d javac is installed

How?? Please explain better!

Cos I've tried changing the directory as in -- C:\Program Files (x86)\Java\jdk1.8.0_25\

But it tells me 'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

I've downloaded IDE for netbeans

GodMode:
Download an IDE for java... eclipse or netbeans...

I'm VERY NEW to programming, and I want to learn it. Going through some sites, I was advised to learn Java first. (I have like 20% HTML knowledge already). I've been doing and running the Java "hello World program" but I'm just finding something crazy about the program. Please I'd like your Nairaland programmers (gurus) to please walk me through the process of creating a Java Hello World. java program. Then maybe advice me on more things to learn with.
I've tried learning with http://docs.oracle.com/ java course, but their some things I think I still need "some sort of personal touch" to learn... and I'm REALLY WILLINGLY TO LEARN.
Tip -- I'd like to create an Android app... but from the SCRATCH.

Amber, who recently split from hubby Wiz Khalifa, is joined by gal pal Blac Chyna for their bouncy take on a workout video. This one is of the b*ooty kind.
