A Basic Simple Problem

[Gary Farms]

I wrote a simple "Hello World " java program. It looks as follows:
public class Welcome
{
public static void main String args[] )
{
System.out.println("Hello World!" );
}
}
It compiles OK, but when I attempt to run it, I get an error stating:
"Exception in thread "main" java.lang.NosuchMethodError: main
Why am I getting this error??

This is probably a classpath problem. On the command line before you type java HelloWorld, set the classpath to include the current directory like this:
set classpath=%classpath%;.
Don't leave out the dot at the end, that is the current directory symbol.

Check your classpath of java library and bin.
It should be set as
PATH = c:\jdk1.3\bin;
SET CLASSPATH = C:\jdk1.3\lib;
SET JAVA_HOME = C:\jdk1.3;

Hi!,
There is an error in your program...
public class Welcome
{
public static void main String args[] )
{
System.out.println("Hello World!" );
}
}

Should be

class Welcome
{
public static void main(String[] args)
{
System.out.println("Hello World!");
}
}

You have forgot "(String[] args)"
