Question

Assume you are given a class called Tyre that has two attributes type and size of type String. There is another class called Car that has three attributes name of type String, num of type integer and t of type Tyre, the constructor of class Car can be written as:

 
  1. public Car(String n, int no, String t1, String s)

    { name = n;

    num = no;

    t = new Tyre(t1, s);

    }

     
  2. public Car(String n, int no)

    { name = n;

    num = no;

    type = “Unknown”;

    size = “Unassigned”;

    }

     
  3. public Car(String t, String s)

    { name = “Unknown”;

       num = “Unknown”;

       type = t;

       size = s;

     }

     
  4. public Car(String n, int no, Tyre tyre)

    { name = n;

    num = no;

    t.type = tyre.type;

    t.num = tyre.num;

    }

Assume you are given a class called Tyre that has two attributes type and size of type String. There is another class called Car that
has three attributes name of type String, num of type integer and t of type Tyre, the constructor of class Car can be written as:
public Car(String n, int no, String t1, String s)
{ name = n;
A) num = no;
t= new Tyre(t1, s);
}
public Car(String n, int no)
{ name = n;
num = no;
type = "Unknown";
size = "Unassigned";
}
public Car(String t, String s)
{ name = "Unknown";
num = "Unknown";
type = t;
size = s;
}
public Car(String n, int no, Tyre tyre)
{ name = n;
num - no;
t.type = tyre.type;
t.num - tyre.num;
}
