Question

What is the finished code in Java? I posted this earlier and it was wrong.... try and use as basic terms as possible to.

package labQuadrotors;

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;
}

}

What is a Quadrotor? Check out this video Download Quadrotor.java In the same directory create a file called QuadrotorApp. It includes the main method In main do the following: Create a List of Quadrotors and initialize it with 6quadrotors like this: List

Explanation / Answer

here is your class : --------->>>>>>>>>

import java.util.*;

public class QuadrotoApp{
private static void changeOrientation(List<Quadrotor> rotors){
  int temp;
  for(int i = 0;i<rotors.size();i++){
   temp = rotors.get(i).getX();
   rotors.get(i).setX(rotors.get(i).getY());
   rotors.get(i).setY(temp);
  }
}
public static void main(String[] args) {
  List<Quadrotor> rotors = new ArrayList<>(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)));
  //first uncoment this and comment above line
  /*List<Quadrotor> 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);
  changeOrientation(rotors);
  System.out.println(rotors);
  Quadrotor searchItem = new Quadrotor(4,6,4);
  if(rotors.contains(searchItem)){
   System.out.println("rotors does contains "+searchItem);
  }
  System.out.println(" Number of rotors "+rotors.size()+" ");
  try{
   rotors.remove(searchItem);
  }catch(Exception e){
   System.out.println(" You are using only list not ArrayList");
  }
  System.out.println(rotors);
  rotors.remove(0);
  System.out.println(rotors);
}
}
