JAVA

Create a ComplexNumber class with variables real and imaginary. The values can be positive or negative.

Create a Constructor method for this class.

Create a toString() method which shows the ComplexNumber in this format, a + bi, or a - bi or -a + bi or -a - bi, depending on the values of real and imaginary. For fractions show 2 digits after the decimal point.

Create add, sub and multiply methods which adds, subtracts and multiply two ComplexNumber. These functions should take a single ComplexNumber parameter and update the current ComplexNumber with the new value. Following are the rules for add, sub and multiply: (a+bi) + (c+di) = (a+c) + (b+d)i (a+bi)(c+di) = ac + adi + bci - bd

Create a driver class which generates several Complex numbers and test the created methods.
