Hi P T

The below code does the swapping, which uses the simple swapping logic, i don't think Java provides
any API for that. Let me know, what you asked is this or not.

   		Coord   coord1 = new Coord(10,20); // Assume you have constructor which takes X, Y, here X = 10 and Y = 20
		Coord   coord2 = new Coord(30,40);
		
		Coord   temp = new Coord();//Constructor with no parameters.
		
		temp.X = coord1.X;
		temp.Y = coord1.y;
		
		coord1.X = coord2.X;
		coord1.Y = coord2.Y;
		
		coord2.X = temp.X;
		coord2.Y = temp.Y;
		
		
   

Cheers
