我无法在intelliJ中运行该程序

Question

I created a project unchecked (Create project form template) and added new class named demo. but when after compiling, I couldn't run the code intellij didin't show me result. "Edit configuration" only appeared like this:

I don't know what to do :( I saw someone run the code using Intellij without writing package. So I don't think that it doesn't work because I didn't write package. What can I do?

Answer 1

You are missing the String[] args parameter in your main method:

public static void main(String[] args) {

}

Answer 2

Add the args parameter to the main method. Then right click into the editor -> and select "Run demo.main()"
