The program runs fine under eclipse, but not under cmd

viruser

The simplest Welcome.java works fine under eclipse,
But under cmd, compiling javac is no problem, but when java Welcome, it appears
Exception int thread "main" java.lang.NoClassDefFoundError: Welcome
error.
May I ask how is this going?

With environmental parameters

viruser

Environment variable?
Already set up!
Can you say more upstairs!

This issue needs to be researched by yourself, and these things will not happen again

Source code?

Must be a problem with environment variables
Check your classpath
Post your environment variables

nuaa31203

Configure Classpath or add classpath to your command line

Add ".," to the classpath.path environment variable. It may be that you ignore the current path.

".;" Is wrong.
