2.042

2.143

1st output expected 2.043. can me in this?

from docs decimalformat:

decimalformat provides rounding modes defined in roundingmode formatting. default, uses roundingmode.half_even.

it sounds need:

dfform.setroundingmode(roundingmode.half_up); 

that's after you've fixed code call format on actual numbers, mind you:

bigdecimal value1 = new bigdecimal("2.0425");         bigdecimal value2 = new bigdecimal("2.1425"); 

if use double values, you'll still see 2.042, nearest double 2.0425 2.042499999999999982236431605997495353221893310546875.
