Hello Wedo Ru

Your vehicle has a color. Because it is not private you can assign a value to color.

Just try this:
System.out.println(v1.color);
v1.color = "red";
System.out.println(v1.color);

Maybe not the best example but it shows you what you can do with fields (variables in a class).

If color would be private you would need methods to manipulate/return the value (see lesson about getter/setter).
