Problem with Hello World

[Terry Wynn]

Just getting started. I got the following:

C:\Jplan>javac hello.java

C:\Jplan>java hello.java
Exception in thread "main" java.lang.NoClassDefFoundError: hello/java
Caused by: java.lang.ClassNotFoundException: hello.java
at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
at java.lang.ClassLoader.loadClass(ClassLoader.java:303)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:316)
Could not find the main class: hello.java. Program will exit.


So I can compile, but not execute.

The startup at the Cattle Drive indicates that I need to set my CLASSPATH to

.;C\Jplan

I believe I have.

Although I don't know how to check that.

Thanks in advance for the help.


Program is


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


located in c:\Jplan\hello.java

Rather than running it with:

C:\Jplan>java hello.java

Use:

C:\Jplan>java hello

Whoopsie.

Thank you very much. Works fine.


Sorry to be THIS stupid. I am sure none of you did anything like this in the beginning.

To be honest, I've been studying Java for about a year now and I STILL do that sometimes. I will stare at the command line for about 5 seconds wondering what happened, then proceed to laugh at myself.
