Compiles but won't run

[Alexishy]

I enrolled in a summer Computer Programming I class, and we were instructed to create, compile, and run the following program. It compiles just fine, but when I go to run it, Window's Installer pops up. I can't do anthing with that except exit out. Why is it not running?


//************************************************** ************************************************** *****************************

public class Lincoln
{
//-------------------------------------------------------------------------------------------------------------------------
// Prints a presidential quote.
//-------------------------------------------------------------------------------------------------------------------------
public static void main (String [] args)
{
System.out.println ("A quote by Abraham Lincoln:");

System.out.println ("Whatever you are, be a good one.");
}
}

[Dark]

How are you trying to run it? And what do you mean that it brings up the windows installer?

[wookyoo]

The code works fine. I just run it

[Alexishy]

I type in java Lincoln into the command prompt and hit enter. Then it asks if I want this program to make changes to the computer, and I click "Yes." Then This pops up: Windows ® Installer. V 5.0.7600.16385

The Only button to press is "Okay."

[sunde887]

It shouldn't be asking you if you want to allow access, does it do anything if you say no? You are compilig and running with cmd?

[Dark]

Have you configured your Java SDK to work in the command prompt?

[Alexishy]

It tells me that access is denied if I click "No." Yes, I am using CMD. Dark, by "configure," do you mean "after downloading, change the path?" Because I don't quite understand what you mean.

[Dark]

Well yeah, does your CMD have the proper paths set up? I'm not really sure why it would bring up an installer if you had it configured correctly.

[Alexishy]

My instructor posted the link to a video tutorial on how to do that. I typed in dir /s java.exe, then marked the c:.......bin., went to environment variables, and edited it into the Path.

[sunde887]

So your path variable points to the bin folder(which contains the javac file), you generated the .class file correctly? The basics of downloading Jdk is download, install, set path, set classpath of you want, then you should be good to start. Would you mind typing out the step by step process the video took you through?

[Alexishy]

At java.sun.com, download the JDK, install it, go to the Command Prompt; type in cd/, to get to c:, then type in "dir /s java.exe." After the computer gives the c:.....bin, then mark it and click on start, then my computer, then system properties, then advanced, then enviroment variables. Go to Path on the bottom and click edit. This video said to go to the end of the text, type ";" and paste what was marked. I have since read another tutorial and moved it to the front of the path, so that it starts: .;c:.....bin; Then click ok three times. The more recent tutorial said to go into command prompt and type: "javac -version" and "java -version" to make sure everything was installed. I did that, too. One more thing: I stored the java file and the program in a CPI file in C:. So, the instructions for compiling and running the program say to change the prompt to C:\CPI. As I said, it does compile. Hope this was enough information.

[Dark]

Did javac -version and java -version work?

[sunde887]

Whenever I've installed the Jdk I out the bin path in a variable at the top called PATH. Check near the end of this video.

[Alexishy]

Yes, Dark, it did work. sunde887, I will check out that video. Thank you both.
