Can't get even a hello world program to work

Question

Hello,
I am new to java and have written the following and saved it
to hello.java:
public class hello
public static void main(String[] args)
System.out.println("Hello, world");
Then I run javac as follows:
javac hello.java
No errors, so I type:
java hello
and I get
Exception in thread "main" java.lang.NoClassDefFoundError: hello
I have been careful for upper and lower case.
What am I missing?
I just installed java on this machine.
Thanks,
Mike

Answer 1

Do this instead:java -cp . hello... note the dot following the '-cp' flag. The Java virtual machine needs to
know where your classes are stored, i.e. it doesn't assume a concept
of a 'current working directory'. The '-cp' flag is followed by a list of dirs
(here it's just the current directory '.') that store .class files.
kind regards,
