변수의 scope와 static

1)

public class VariableScopeExam{
    static int value = 10;
    public static void main(String []args){
        System.out.println(VariableScopeExam.value);
    }
}

2)

Car.java

public class Car{
    static int wheelCount;
}

StaticExam.java

public class StaticExam{
    public static void main(String []args){
        Car taxi = new Car();
        Car suv = new Car();
        
        taxi.wheelCount = 10;
        suv.wheelCount = 4;
        
        System.out.println("taxi의 바퀴수:"+ taxi.wheelCount);
        System.out.println("suv의 바퀴수:"+ suv.wheelCount);
    }
}
