To run a java program we type "java MainClassName" in terminal window. What is happening behind the scenes when we type this command. Are running our program with JRE when we type this command?
There is a java in the JDK graphics craig showed and it is out of JRE is that the same java we used to run our code. if yes why it is out of JRE while JRE is important to run java code?
Please explain!

The "There is a java" part I do not really understand. what do you mean by "a java"?

there is a java in the graphical display of the java platform which is outside the JRE.
