Using Terminal in Mac OSX to program and test java

I bought a book on java and it says I should not use a JDK like Net Beans when first learning java.
Right or wrong I would like to know how to use terminal to program and compile simple scripts.
So my question is:
How do you go about setting up the computer to use terminal to write and compile a java program? I know my Mac sees java in terminal because tells me Im running "version 1.5.0_07"
I just need a link to some info on how to get started using Terminal for my command line with java.
I think if I could get a path set up from the command line to my text file and have javac see it I would be in pretty good shape. At least for now.
If I use a text saved plain text file (.java) how do I set up a path to it using javac from the command line?
Where can I find or link to this kind of info?

Hi,
seems like you have not tried out a few things.
1. Set up the JAVA_HOME environment variable. (I assume you pretty much know it) the folder where java is installed.
2. set up the environment variable to point to the bin folder inside the java installation folder.
3. open up a console (it seems from your post you know it.), type java -version see the java version.
4. type in javac, press enter: you should get the javac options.
5. type in java, you should see the java options.
Write your programs in a text editor, save it as somename.java.
open a console, change to the directory containing the java file.
type: javac somename.java <PRESS ENTER>
you should get the compilation errors if any.
if not
type in: java somename.java
Hope this helps.

AyusmanStep 1 and 2 are generally not needed. Mac OS X comes with Java configured up and running right out of the box.

I think they mean IDE, considering that Java is the JDK. And I agree with that idea, not just for Java, but for any language.

There isn't anything to setup. Just run Terminal and type "vi hello.java" or "nano hello.java". To compile, type "javac hello.java".

That is not necessarily a big question, just fundamental. Try Google. It becomes second nature after a couple of decades so I don't really know where to tell you to look. People do tend to have a big list of links, hopefully they can contribute some.

It should already be in your path.

Try Google. People like it. You should find many pages similar to this.

HT5527 If I have both Mac OSX for laptop and desktop, and iPhones/iPads with OS 5 and later, does a single purchase on one of them cover all of them?

If I have both Mac OSX for laptop and desktop, and iPhones/iPads with OS 5 and later, does a single purchase to expand iCloud on one of the devices apply to all of them?

Yes, it's icloud's storage you will be expanding. All devices logged into an account will be able to use that storage.

Mac OS X 10.5 Leopard installation system requirements
http://support.apple.com/kb/TA24950
Leopard is no longer available at the Apple Store but may be available by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753).
If you can't obtain a retail install DVD from Apple, look on eBay or Google the installer part numbers to possibly find at an on-line store. Here's what to look for:
MB427Z/A Leopard 10.5.1 install DVD
MB576Z/A Leopard 10.5.4 install DVD
MB021Z/A Leopard 10.5.6 install DVD (single user)
MB022Z/A Leopard 10.5.6 install DVD (5-user family pack)

After you install the base 10.5, download & install the 10.5.8 combo update at http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update
The DVD should look like this
Caution - Leopard does not support classic mode. So, if you currently open OS 9 apps in classic mode, you won't be able to do this if you upgrade to Leopard.

I'm using FF for Mac 3.6.13 and everytime I open a new window or tab the image of what I see is tiny which requires me to click Command + to enlarge it. The actual page is normal size, but its the image of the page that opens tiny.

I'm using FF for Mac 3.6.13 and every time I open a new window or tab the image of what I see is tiny which then requires me to click Command + to enlarge it about 4 or 5 times. The actual page is normal size, but its the image (what I see) of the page that is tiny.

Thanks but Command 0 on a Mac only makes a temporary change to that one page. The link you provided doesn't show how to make a permanent change. Do you know how to permanently change this so I don't have to do it to every new page?
Thank you.

I have got two questions: 1. Can I use a wireless Mouse with an I Pad? 2. Is there Nano-Technology in use in Apple / Mac - Computers, I Pads and or Phones?
Thanks Roland

There actually is a type of "pointer" native to iOS. it's part of the AssistiveTouch feature, used to replicate multitouch gestures with one finger. You just can't control it with a mouse.
Anyway, as far as I can discern the iPad does not use nanotechnology in any part of its construction.

Difference between a java program and a java class

Hi there,
What is the difference between a java program and a java class?

HI,
A java class is an object - described in a .class file - which has been given properties and behaviours and which can be instantiated in a program.
A java program( application ) consists of at least one class (one of which must be declared public) and which executes its main() method ( of the public class ) when it is started.
Every program is a class but not every class is a program.
Examples:
A java program
// this simple program will print out the first command line argument you put
// in after calling : java ScreenWriter "arguments"
class ScreenWriter
public static void main( String [] args )
if( args.length > 0 )
System.out.println( args[0] );
A java class
//the Math class is already defined in the java.lang package
//and contains a constant for PI
//So I can include the Math class with the PI constant in my simple program
//and now I have a program that involves my ScreenWriter class and the Math class too.
class ScreenWriter
public static void main( String [] args )
if( args.length > 0 )
System.out.println( args[0] );
System.out.println( "The value of Pi is: " + Math.PI );
When you see package and import declarations at the start of a program they are there to ensure the compiler knows which classes are used in the program.
Hope that helps,
Terry

Can ABAP program and a Java apps access the same DB table?

If an ABAP program and a Java apps access the same DB table, how does the Enqueue services from ABAP and Java communicate with each other to ensure locking consistency (if they even communicate with each otehr at all)?
Or there wont be such situation because there are separate schema for ABAP stack and Java stack?
Your help is greatly appreciated.

Hello!
A while ago I was a subject to criticism too for not granting points to helpfull answers. I appeared to be ungratefull, but I'm actually not (I guess the same goes for Vincent). I absolutely agree that good people who provide helpfull answers deserve (at least) points, but I didn't quite get the whole idea with points untill I was explicitly warned. I took some time to correct this and I granted points for all my past questions, generously, with "interest rates" for waiting.
My point is:
The pointing system is good, but unintuitive and not documented. I suggested this at that time, and I see that nothing has changed since. I see also that I'm not the only one who has experienced missunderstandings.
I repeat the message to SDN people: Please provide some info on pointing system! A few sentences behind a "What's this?" link would do. It's not such a hard work.
Thanks!
Kind regards,
Igor Barbaric

Troubles using Flash on Mac OSX

Operating System: Mac OSx 10.5.8
Web Browser: Firefox 16.0.2
Flash Player Version: 10.3.183.90
It seems to me I have the latest available flash player version for my operating system but I am still unable to view certain videos or strems.
When I attempt to watch a video I receive the following message "You need Adobe Flash Player to watch this video. Download it from Adobe."
I have uninstalled my flash player using the uninstall program for the version I have, then reinstalled the flash player. The installation goes fine but I still receive this message when trying to watch a video.
On this site here: http://helpx.adobe.com/flash-player.html It tells me I do not have the latest version of flash player but none of the later versions are supported for my operating system.
Am I missing something here?
Thanks in advance for your help.

Yes and no...
If it's a Core™Duo, you're stuck with 10.5.8, because it's a 32 bit processor.
If it's a Core2™Duo, then you can upgrade to Snow Leopard for just $19.99 through Apple.
Either way, 10.3.183.90 is the end of the line for Leopard.
10.5.8, being a "universal binary" OS, has to have compatiblity for PowerPC Macs, and that limits how far it can go with anything. Office 2004 is the newest version that will run on Leopard, and it CAN'T create .doxc, .xlsx. or .pptx documents that 2008 and 2011 use.
Safari can't go higher than 5, Firefox is limited to 16. There's just a lot that 10.5 can't and won't handle.

Insufficient disk space using server103linux32 on Mac OSX

I am trying to install Oracle Workshop for Weblogic 10.3 on Mac OSX using the Linux version of the application. After extracting and executing "java -jar installer.jar", the GUI installer opens and appears to run fine, but after the last dialog, I get the following error:
Insufficient disk space! The installer requires:
617MB for the BEA Home at /Users/cburleson/bea,
548MB for the product at /Users/cburleson/bea/tools/eclipse_pkgs/2.0...
867MB temporary work space at /Users/cburleson/Downloads/server103linux32
There is only 868MB available at /.
"df" command in my terminal shows that I have only used 60% capacity on my volume. I clearly have more than 868MB available. Does anybody know what the deal is or how to get around this?

jlarechiga, it does not work on my snow leopard system.
tried to install using : Erwin Morales' Blog
http://blogs.oracle.com/emorales/2009/06/weblogic_over_mac_os_x.html
server103_generic.jar gives the similar error stating only 1MB free (even when you run : sudo java to start installer)

Mac OSX 10.9 and HP Officejet Pro 8100 Compatibility

Can we please get a driver for the HP Officejet Pro 8100 that is compatible with the Mac OSX 10.9? I bought the printer so that my roommate and I could share it to print wirelessly, but I am unable to do that without a compatible driver. Please develop one as soon as possible!
Thanks!

Hi,
The Drivers are available via Apple Software Update,
In order to configure it wirelessly you may use the HP Easy Wireless Install app.
You may find a step by step guide in the following document:
h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?sp4ts.oid=4337543&spf_p.tpst...
The app iself can be downloaded from the Mac App Store:
https://itunes.apple.com/us/app/hp-easy-wireless-setup/id876495880?mt=12
If you experience any issues while trying to locate the pritner during the wireless configuration. restoring the network defaults for the printer can be done by pressing and holding both the Cancel ( ), the Wireless ( ), and the Power ( ) buttons for three seconds.
