copied!<p>This is a CSE homework, I was hoping there might be some friendly guys and gals out there that might take a quick look and see if it looks good to turn in, thanks Y'all. </p> <p>Here are the instructions and the code I wrote, </p> <p>-Kyle</p> <p>write a ComplexNumber class with:</p> <p>(1) a constructor which does not take any parameters (where the default value of a complex number should be 0 + 0i in this case.)</p> <p>(2) another constructor that takes real and imaginary parts of type int as parameters</p> <p>(3) an add method which takes another complex number, c2, as a parameter and adds c2 to the current complex number, which is this, and returns the resulting complex number. (4) a subtract method which takes another complex number, c2, as a parameter and subtracts c2 from the current complex number this, and returns the resulting complex number.</p> <p>(5) a multiply method which takes another complex number, c2, as a parameter and multiplies c2 with the current complex number this, and returns the resulting complex number.</p> <p>(6) a divide method which takes another complex number, c2, as a parameter and divides the current complex number this by c2, and returns the resulting complex number.</p> <p>(7) a toString1 method that will print a String that is the current complex number in the form of a + bi, where a and b will be the values of the real and imaginary parts of the natural number.</p> <pre><code>/* * Kyle Arthur Benzle * CSE 214 * 10/13/9 * Tagore * * This program takes two int variables and performs * four mathematical operations (+, -, *, /) to them before returning the result from a toString1 method. */ //our first class Complex# public class ComplexNumber { // two int variables real and imagine int real; int imagine; // Constructor, no parameters, setting our complex number equal to o + oi ComplexNumber() { real = 0; imagine = 0; } // Constructor taking two int variables as parameters.
