constructor in java

class another{
int x,y;
another(int a, int b){
x = a;
y = b;
}
another(){
}
int area(){
int ar = x*y;
return(ar);
}
}
public class Construct{
   public static void main(String[] args)
   {
  another b = new another();
  b.x = 2;
  b.y = 3;
  System.out.println("Area of rectangle : " + b.area());
  System.out.println("Value of y in another class : " + b.y);
  another a = new another(1,1);
  System.out.println("Area of rectangle : " + a.area());
  System.out.println("Value of x in another class : " + a.x);
   }
}

Output:
--------------
Area of rectangle: 6
Value of y in another class: 3
Area of rectangle: 1
Value of x in another class: 1
