NEED HELP :(

Hi All!
I'm very new to this and new to Java I'm taking a computer science program in school and have an assignment to do and I'm so lost I really don't understand anything at all :(. I have to Design and implement a class called Car that contains instance data that represents the make, model, and year of the car. Define the Car constructor to initalize these values. Include getter and setter methods for all instance data, and a to-String nethod that returns a one-line description of the car. Create a driver class called CarTest, who's main method instantiates and updates several Car objects.
I have no clue what to do!

Someone please help me out!
