can i get help with this one please. here is the starter class

public class Quadrotor { private int x; private int y; private int z;

public Quadrotor(int x, int y, int z) { this.x = x; this.y = y; this.z = z; }

public int getX() { return x; }

public void setX(int x) { this.x = x; }

public int getY() { return y; }

public void setY(int y) { this.y = y; }

public int getZ() { return z; }

public void setZ(int z) { this.z = z; }

@Override public String toString() { return "QR:" + x + "/" + y + "/" + z; }

@Override public int hashCode() { final int prime = 31; int result = 1; result = prime * result + x; result = prime * result + y; result = prime * result + z; return result; }

@Override public boolean equals(Object obj) { if (!(obj instanceof Quadrotor)) return false; Quadrotor other = (Quadrotor) obj; if (x == other.x && y == other.y && z == other.z) return true; return false; }

}

And what i've got so far

public class QuadrotorApp { public static void main(String[] args){ List rotors = Arrays.asList( new Quadrotor(2,4,2), new Quadrotor(3,4,4), new Quadrotor(4,4,6), new Quadrotor(5,4,2), new Quadrotor(6,4,4), new Quadrotor(7,4,6)); System.out.println(rotors.toString()); } }
