IntelliJ cannot found my main class

Question

I do not know why it cannot found main class. In fact, I use terminal to run this, it works.

You're trying to run a class called `Test` but your class name is `HelloWorld`... — Reimeus, Jun 09 '17 at 17:45

The error message is more precisely:

Error: Could not find or load main class Test

Emphasis mine. In the top-right corner, notice the dropdown labeled "Test", with a small red cross on it. That's the currently active run configuration. It's a previous configuration that you used that's no longer valid.

An easy way to run this program is using keyboard shortcuts:

Place the cursor inside the main method
Press Control Shift F10 at the same time

This will create a new run configuration, to execute the class you are currently in. After this is done, observe the label on the dropdown in the top-right corner change to "HelloWorld", the name of your class.
