Class without default constructor

    
public  class  MyClass
{
      public  MyClass(  int  x,  int  y  )
      {
            this.x  =  x;
            this.y  =  y;
      }

      public  int  x;
      public  int  y;
}

public  class  EntryPoint
{
      static  void  Main()
      {
            //  We  can't  do  this!
            //  MyClass  objA  =  new  MyClass();

            MyClass  objA  =  new  MyClass(  1,  2  );
            System.Console.WriteLine(  "objA.x  =  {0},  objA.y  =  {1}",
                                                                objA.x,  objA.y  );
      }
}
    
   
  
   

objA.x = 1, objA.y = 2
