Question

Directions :: Write a Ship class. Ship will have x, y, and speed properties. x, y, and speed are integer numbers. You must provide 3 constructors, an equals, and a toString for class Ship.

One constructor must be a default.

One constructor must be an x and y only constructor.

One constructor must be an x, y, and speed constructor.

Provide all accessor and mutator methods needed to complete the class.

Add a increaseSpeed method to make the Ship speed up according to a parameter passed in.

Provide an equals method to determine if 2 Ships are the same(i.e. in the same location).

You also must provide a toString() method.

The toString() should return the x, y, and speed of the Ship.



In order to test your newly created class, you must create another class called ShipRunner. There you will code in the main method and create at least 2 Ship objects (although you can create more if you like), using the constructors you created in the Ship class. Then you will print them out using the toString method and compare them with the equals method.



I'm trying to make an equals method I just don't know how to​

Answer 1

Answer: Assuming this is in the java language.. the equals() would be

Step-by-step explanation:

public boolean equals(Object o){

if(o == this){

return true;

}

if (!(o instanceof Ship)) {

return false;

}

Ship s = (Ship) o;

return s.x == this.x && s.y == this.y && s.speed == this.speed;

}
