Error message when running simple Java pgm
 

used following in MS-DOSS command window

public class Welcome1 {
/*method*/
public static void main( String args [])
{
System.out.println( "Welcome to Java Programming!" );
}/*end main*/
}/*end class Welcome1*/

It was taken as an elementry example of a Jova pgm.

I saved it as Welcome1.java and used the MS-DOS command line, > java Welcome1 There was a momentary hesitation and I received the following Error message

Exception in thread "main" Java.lang.NoClassDefFoundError:Welcome1

I'm trying to learn Java on my own. I'd like some help in taking this first step. Any suggestions????

Heres a dumb question... did you compile it first?

Re: Error message when running simple Java pgm
 

use javac Welcome1.java
and then use

java Welcome1

Re: Error message when running simple Java pgm
 

At the dos command prompt I tried "javac Welcome1.java" and I get...... 'javac' is not recognized as an internal or external command, operable program or batch file.

You need to add it to your system variables. It depends on what OS you're running as to how to do this. Or you could just type in the full path name like:

C:\Program Files\Sun\JavaSDK\bin\javac.exe program.java
C:\Program Files\Sun|JavaSDK\bin\java.exe program

Of course, your's is probably different. But youshould get the idea.
