 ### Executing your program
 Now, there's a lot going on here, but don't worry too much about that, we will get into all the details eventually. For now, we will just be happy about having created our first Java program. To run a Java program, the source code needs to be compiled into bytecode, which can be interpreted by the Java Virtual Machine (JVM). There's an explicit way of doing this, via the terminal, and there's an automatic way to do it in VSCode. For now, let's start with the automatic way. To execute your code, press either the triangle-shaped "Run Java" button in the top right-hand corner of your screen, or the grey "Run" command just above the line in your code that includes the call to `main()`. If everything works as it should, you will see a terminal prompt opening on the bottom of your screen, and the message "Hello World!" displayed. Amazing! We have created and run our first Java Program!
