The file name needs to be Magamar.java

Well....

you must have a file name called Magamar.java with your code.

so

( if you are using command line )

#> javac Magamar.java

( it will compile and generate a Magamar.class )

now you must run the code..

# > java -cp . Magamar

The '-cp' option tell the 'java' application where to search for .class files...

if you put '-cp .' ( in windows ) you tell the java so search the .class files in current directory... it may work...

it occurred to me you may have put your class in a package... if so, you may have the proper folder structure, and call the 'javac' and 'java', like '# > javac your.package.structure.ClassName.java and java -cp . your.package.strucutre.ClassName

hope it helps

You should have a file on your pc named Magamar.java

In that file should be the code you wrote in the first post.

Then in the command line you go to the folder that holds the file Magamar.java

Then you type: javac Magamar.java (this will generate a Magamar.class file)

Then you type: java Magamar

ok.. my english is not so good.. maybe I was not able to express me well...

lets do a step by step:

( I suppose you have the JDK installed, so you can use the 'Javac' and 'Java' commands from your command prompt. )

1) Create your class ( Magamar ): Create a file named 'Magamar.java' ( maybe in c:\javaproject, so it will be c:\javaproject\Magamar.java )

2) Edit the file and put the code into it:

public class Magamar
{
	//this is the main method
    public static void main (String[] args)
    {
	//this prints whatever is below.
	System.out.println("Hello World");
    }
}

3) open the command prompt ( windows ) or console ( linux ) and use 'cd c:\javaproject' ( you must be in the same folder as your Magamar.java file )

4) Execute the 'javac' command:

#> javac Magamar.java

( you may notice it will create a file called Magamar.class in the same directory )

5) run your program ( use 'java' command )

#> java -cp . Magamar

- it will call the java 'interpreter' ( its the java virtual machine btw ) telling to execute the Magamar.class file

You must see the 'Hello World' string on console.

Are you using some IDE to develop? or are you developing on 'notepad' or some text editor?

You should have a file on your pc named Magamar.java

In that file should be the code you wrote in the first post.

Then in the command line you go to the folder that holds the file Magamar.java

Then you type: javac Magamar.java (this will generate a Magamar.class file)

Then you type: java Magamar

Axel, if you dont use the '-cp' command you will get the error :

C:\>java Magamar
Error: Could not find or load main class Magamar

I think you must tell the virtual machine where to look for your class files, unless it is in your default classpath..... :)
