Hi there, my professor gave us a classwork about classes. He have us a complex number class or complex number class demo and he told us to finish it by adding strings and classes. In short he gave us-

ComplexNumber cn1 = new ComplexNumber (4, 5);

ComplexNumber cn2 = new ComplexNumber (3, -2);

ComplexNumber cn3, cn4, cn5, cn6, cn7;

System.out.println ("First ComplexNumber number: " + cn1);

System.out.println ("Second ComplexNumber number: " + cn2);

if (cn1.equals(cn2))

System.out.println ("cn1 and cn2 are equal.");

else

System.out.println ("cn1 and cn2 are NOT equal.");

cn4 = cn1.add(cn2);

cn5 = cn1.subtract(cn2);

cn6 = cn1.multiply(cn2);

cn7 = cn1.divide(cn2);

System.out.println ("cn1 + cn2: " + cn4);

System.out.println ("cn1 - cn2: " + cn5);

System.out.println ("cn1 * cn2: " + cn6);

System.out.println ("cn1 / cn2: " + cn7);

}

}

As you can see in the above code he wants us to create complex number class and add some codes in it. I would recommend you to copy and paste this code in your compiler and see what the code or what the new class needs to give the outputs in above code
