non-static variable object1 cannot be referenced from a static context

Question

I\'m having a little trouble getting my application to work.

I get the error: error: non-static variable object1 cannot be referenced from a static context

Answer 1

public object object1 make this as public static object object1;

You can not refer non-static class variables inside static method.

Answer 2

Your "main" method is considered static and so it can only access static objects, Try declaring your object1 static:

public static Object object1;

edit: if you need 2 objects there is no harm in doing:

public static Object object1;
public static Object object2;

Do not get mixed up between a static field and a static class (like a Singleton). Static in this context (static Object object1) only means that there is one and only instance of that object per instance of your class car_game, in the case above their would be 2 instance of Object (object1 and object2) even if you would instanciate 10 object of type "car_game".

For example if i'd do:

car_game carGameObject1 = new car_game();
car_game carGameObject2 = new car_game();
carGameObject1.setObject1("this is one");

And then:

System.out.println(carGameObject2.getObject1());

it would print "this is one" because since object1 is static all instances of the class in which that fields belong will share the same instance.
