Im kind of wanting to learn java but have been so excited about using linux (Mandrake 9.2). I use BlueJ a debuging app for java.
How can I porgram java in Linux?

I think the first step would be to install the latest java SDK... from java.sun.com.. Then, buy a few books on the subject, or go through the Java Tutorial at the java.sun.com site.

Seeing as how Java is meant to be platform-independent (which USUALLY is the case and can be trusted), there isn't any difference from java in linux to any other O/S....

Hi,

i'm actually learning java with "thinking in java" (you can download it for free at
www.briuceeckel.com).

It's much more detailed than the sun tutorial.

The Sun tutorials on Swing are very good, though I agree their core programming ones are not great. Check these two:

http://java.sun.com/products/jlf/ed2/book/index.html

I think I downloaded the wrong one on the java.sun site
The file name is j2eesdk-1_4-dr-linux-eval 130mb (took me 13hrs to downlad)
how do I install this, I can't find instructions on the site

Your probably best downloading the J2SE (Java 2 Standard Edition) SDK, the RPM for Linux is about 32mb.

bugger!

There are several versions of the Java SDK, for different situations. The J2EE own that you downloaded is for enterprise servers, with support for Servlets/JSP and other high-end network application stuff. You should be using the J2SE first, as that is the bare-bones platform.

FIY, there's also a J2ME, which is the Micro Edition, for running Java on devices such as PDAs and mobile phones.

Basically, after you download and install JDK and stuffs like that, the core Java programming is the same on both windows and Linux.

I installed it but I can not run javac unless I go /home/me/j2sdketc/bin/javac
How do I just make it so that I just type javac
I installed as a user not as root, should I have installed as root?

You need to add your J2SDK bin directory to the PATH.

export PATH=$PATH:/home/me/j2sdketc/bin

Thanks moeminhtun thats solved my problem aswell.

Yes thanks anyway
I did it another way

PATH=/home/me/j2sdk/bin:$PATH

Im trying to do this


class Hello
{
public static void main (String[] args)
{
int minute, hour;
minute = "59";
hour = "11";
System.out.print ("The time is ");
System.out.print (hour);
System.out.print (":");
System.out.print (minute);
System.out.print (".");
}
}
but it doesn't work says "incompatible types - found java.lang.String but expected int"

If I use string it goes but why not with a integer?

Wow, it has been way too long since I did any coding in Java if I cant answer that easy question. I know that it is because of the way your value is assigned. The error message states that pretty clearly, that is one great thing about java compilers. It says it was expecting an integer, but you gave it a string. If I remember correctly, when assigning a value to an integer variable you dont use quotes. I am not certain because it has been too long That, and when I write code I dont even think about the basics anymore, I just do them.

Your question is not even close to a linux question, that is just a mistake in your code.
