A class called MyPolynomial, which models polynomials of degree-n (see equation), is designed as shown in the class diagram.

It contains:  An instance variable named coeffs, which stores the coefficients of the n-degree polynomial in a double array of size n+1, where c0 is kept at index 0.  A constructor MyPolynomial(coeffs:double...) that takes a variable number of doubles to initialize the coeffs array, where the first argument corresponds to c0.  The three dots is known as varargs (variable number of arguments), which is a new feature introduced in JDK 1.5. It accepts an array or a sequence of comma-separated arguments. The compiler automatically packs the comma-separated arguments in an array. The three dots can only be used for the last argument of the method. Hints: public class MyPolynomial { private double[] coeffs; public MyPolynomial(double... coeffs) { // varargs this.coeffs = coeffs; // varargs is treated as array } ...... } // Test program // Can invoke with a variable number of arguments MyPolynomial p1 = new MyPolynomial(1.1, 2.2, 3.3); MyPolynomial p1 = new MyPolynomial(1.1, 2.2, 3.3, 4.4, 5.5); // Can also invoke with an array Double coeffs = {1.2, 3.4, 5.6, 7.8} MyPolynomial p2 = new MyPolynomial(coeffs);  A method getDegree() that returns the degree of this polynomial.  A method toString() that returns "cnx^n+cn-1x^(n-1)+...+c1x+c0".  A method evaluate(double x) that evaluate the polynomial for the given x, by substituting the given x into the polynomial expression.  Methods add() and multiply() that adds and multiplies this polynomial with the given MyPolynomial instance another, and returns this instance that contains the result. You are required to:  Write the MyPolynomial class.  Also write a test driver (called TestMyPolynomial) to test all the public methods defined in the class.
