Answer 1

A valid entry point in java is the main method and it should be public static void:

public static void main(String args[]){
}

So, I think you missed the static keyword in your main method's declaration.
And I would suggest not to write the main method in class TOYOTAcar, but make a separate class with main. There are some well known good practices for designing classes.. one of them is called "Single responsibility". So TOYOTAcar shouldn't be responsible to start your program IMHO.

@Mr Programmer lowercase 'm'! 😝

Answer 3

you spelled it wrong.

its

public static void main(String[] args)
