---I need help in JAVA --- I need to modify the following code to work with complex numbers 

op: Complex Complex Complex

op: Complex double Complex

op: double Complex Complex

the output should be like :

(1 + 2i) + (1 + 3i) = (2 + 5i) (1 + 2i) - (1 + 3i) = (0 + -1i) (1 + 2i) * (1 + 3i) = (-5 + 5i) (1 + 2i) / (1 + 3i) = (0.7 + -0.1i) (1 + 2i) + 5 = (6 + 2i) (1 + 2i) - 5 = (-4 + 2i) (1 + 2i) * 5 = (5 + 10i) (1 + 2i) / 5 = (0.2 + 0.4i) 5 + (1 + 2i) = (6 + 2i) 5 - (1 + 2i) = (4 + -2i) 5 * (1 + 2i) = (5 + 10i) 5 / (1 + 2i) = (1.0 + -2.0i)

*** need imaginary number i ***
