public class Vehicle { int maxSpeed; int wheels; String[] colors = new String[5];//how may colors you want double fuelCapacity; void horn() { System.out.println("Beep!"); } } class MyClass { public static void main(String[ ] args) { Vehicle v1 = new Vehicle(); Vehicle v2 = new Vehicle(); v1.colors[0] = "red"; v1.colors[1] = "blue"; v2.horn(); } }

You can also just pass a new array to v1.color public class Vehicle { int maxSpeed; int wheels; String[] color; double fuelCapacity; void horn() { System.out.println("Beep!"); } } class MyClass { public static void main(String[ ] args) { Vehicle v1 = new Vehicle(); Vehicle v2 = new Vehicle(); v1.color = new String[]{"red", "yellow"}; v2.horn(); } }
