Given:

class Vehicle {

int vno;

String name;

public Vehicle (int vno, String name) {

this.vno = vno,;

this.name = name;

}

public String toString () {

return vno + “:” + name;

}

}

and this code fragment:

Set vehicles = new TreeSet <> ();

vehicles.add(new Vehicle (10123, “Ford”));

vehicles.add(new Vehicle (10124, “BMW”));

System.out.println(vehicles);

What is the result?
