The problem is with following code 

			

			public static void main(String args[]){
			

			DecimalFormat form = new DecimalFormat("0.000");
			

			double f= 99999999999999.999;
			

			Double ft = new Double(f);
			

			System.out.println("Formated :" + form.format(f));
			

			

			}


This always prints 100000000000000.000
What is wrong with the code?

Nothing. IEEE roundoff says that
99999999999999.999 == 100000000000000.000.



Is there that much difference betwen the two values?



If you are doing super-precise mathematical calculations, don't use double values; use Long values and your own "power of ten" multiplier.
