Thread: non-static variable timer cannot be referenced from a static context ERROR HELP!

Hi, I'm trying to program my final project in a class. I was doing fine, and I have it displaying the JFrame fine with all the buttons and the moving cars, but as soon as I try to add actionlisterners to the buttons I've created, I start getting the error messages: non-static variable timer cannot be referenced from a static context. I have no clue how to fix this, and I don't know what I've done wrong, as I've been cross referencing with programs already created in our power points and notes. Can anyone offer me some advice? Below is the code I've written...it starts off with tons of lines of creatings and adding buttons, but the car class, main method, and the action listeners i've attempted to add are all farther down. Any help would be greatly appreciated!

Declaring a variable as final means that the variable's value can not be changed (ie it can not be set to another object). The object that the variable refers to can be changed.
