14.System.out.println("decimalA = " + decimalA);

15.

16.decimalA = decimalA.subtract(decimalB);

17.System.out.println("decimalA = " + decimalA);

18.

19.decimalA = decimalA.divide(decimalB);

20.System.out.println("decimalA = " + decimalA);

21.

22.decimalA = decimalA.pow(2);

23.System.out.println("decimalA = " + decimalA);

24.

25.decimalA = decimalA.negate();

26.System.out.println("decimalA = " + decimalA);

our class result are:

decimalA = 98765432123456799 decimalA = 987654321234567990 decimalA = 987654321234567980 decimalA = 98765432123456798 decimalA = 9754610582533151990855052972412804 decimalA = -9754610582533151990855052972412804
