Question

Hi, how do I i do this step :
To verify that JDK is properly installed, open the Command Prompt, type in javac, and press Enter. (You have to re-open the Command Prompt so the new PATH variable is recognized).
If the JDK has been successfully installed, you will see something similar to the screen below:
i dont know what i have to do there.

The problem is that when i open the javac it closed at the same time
What could be the problem?
Thanks

Hazarding a guess: you need a persistent shell. Assuming Windows...don't just run javac with the "start | run" command or win + r.

Run CMD first. Then at the command prompt type javac.
