How to run java program in command prompt,created by intellij

Question

How do I run my Java program in command prompt, my project was created in Intellij, and I am having difficulties running it in the command prompt...without using the Intellij in creating project,I can run the java program in command prompt.

I do this like this.

java myjava ->this would work. 

but the project created by Intellij,this is the path.

C:\myjava\sampl1\src\com\myexample\test> 

when I issue this command

java myjava -> Error: Could not find or load main class myjava 

but I am inside in that directory.

Thank you in advance.

Three issues:

1. You have to specify the fully qualified class name (that means including the package name) to the java command. It looks like your myjava class is in a package com.myexample.test. So its fully qualified name is com.myexample.test.myjava.

2. When you run the java command you have to be in the directory that is at the base of the package hierarchy (or put that directory on the classpath).

3. You're using the src directory, which contains .java source files, but the java command expects compiled .class files, so you need to use the project's output directory. Its location in your project will depend on your IDE and configuration but it will contain same-named structure as inside src, except with .class files instead of .java files.

In your case, navigate to:

C:\myjava\sampl1\out\production\ 

Then run:

java com.myexample.test.myjava
