when you have finished installing both, start IntelliJ then click create project
I hope that your IntelliJ found automatic like this
Then click Create project from template
click next
Then write Testing or something ells you like. Once you have pressed next it will show up like this:
just click the first arrow so you can see the folder src where it has Main.class
Just write simple Hello World ( you know how to do )
right-click and you can see the green play button Run Main
Good luck!! Let me know if it works!! 👍🏽

962 PointsThe hello world works when i use System.out.println("Hello, World");
HOWEVER... it does not work when I use "console.printf("Hello, my name is Richard"); " like treehouse is telling me to!
Any ideas as to why? Full code below:
package TeamTreeHouse;
import java.io.Console;
/* This is a simple Java program. FileName : "HelloWorld.java". */ public class Main { // Your program begins with a call to main(). // Prints "Hello, World" to the terminal window. public static void main(String[] args) { Console console = System.console(); console.printf("Hello, my name is Richard");
}
}

8,108 PointsWhen you are using treehouse console then you have to call console it's the console java language. When you are using real java language in IDE IntelliJ you call System.out.print("Hello world");
If you feel this is really too hard for you then I strongly to use console and try to fallow the video, about that error maybe you should google it out to find the answer or contact support for bug.

As when i run java Introductions in the console, i get this output:
Picked up JAVA_TOOL_OPTIONS: -Xmx128m
Picked up _JAVA_OPTIONS: -Xmx128m

5,483 PointsThis is how I solved it:
1) Save your code (Control + S or Command +S)
2) Compile your code using "javac Introductions.java" (even if you've done this before, do it again)
3) Run your code using "java Introductions"
4) NOTE: You will STILL see the weird code - but UNDERNEATH IT you should see your code printed out
