Draw the UML class diagram only related to the code below and write an overloading constructor, which accepts two arguments for setting the corresponding fields. The body of this constructor first properly calls another constructor, and then sets another field without using assignment operator. This constructor is for internal usage, within the class itself.

public class City {

protected String cName;

private int cArea;

public City(String cName) {}

void setC (String n) {cName = n;}

void setC (int a) { cArea = a; }

public int getA () { return cArea; }

}
