Question

Java project

Project Complex number class. Tuesday April 17 Write a Complex number class. It will have a default constructor, explicit constructor, and the following methods: read O public Complex add(Complex), public Complex subtract(Complex), public Complex multiply(Complex), public Complex divide(Complex), public boolean equals(complex) and a toString) method. Include get and set methods as well. On my website is an explanation of complex numbers and examples with expected answers along with a main demo program. Study the explanation and use your Book class as a starting point for the Complex number class. Your class should have at least 2 constructors: a default constructor and an explicit constructor with two arguments of type double. Choose descriptive variable names: a, b, c, and d are not acceptable variable names. Do not do arithmetic in the argument to the constructor.
