Java: In command line, Could not find or load main class

Question

I tried to run DependencyParserDemo.java in Stanford NLP parser.

I use Win7, jdk-10.0.1.

In command line:

Javac -cp stanford-parser.jar DependencyParserDemo.java

Works fine, DependencyParserDemo.class generated.

But when I run:

Java -cp stanford-parser.jar DependencyParserDemo

It shows:

Error: Could not find or load mian class DependencyParserDemo
Caused by: java.lang.ClassNotFoundException: DependencyParserDemo

Maybe the classpath setting is wrong?

use java -cp .;stanford-parser.jar DependencyParserDemo . You need to include the current working directory in the classpath — Daniele

You also need the location of the new class in your classpath.

Java -cp stanford-parser.jar;. DependencyParserDemo

Now it gives me: Exception in thread "main" edu.stanford.nlp.io.RuntimeIOException: Error while loading a tragger model(probably missing model file)

Now your code starts. And it has a bug. Time to start understanding what you did.
