What is the value of myBox.size after calling updateBox?

class Box {
    int size;
    Box(int size) {
        this.size = size;
    }
}

public class Test {
    public static void main(String[] args) {
        Box myBox = new Box(5);
        updateBox(myBox);
        System.out.println(myBox.size);
    }

    static void updateBox(Box b) {
        b.size = 10;
    }
}
