Quadratic Solver

The QuadraticSolver class calculates solutions for quadratic equations of the form ax^2 + bx + c = 0. For this class:

• the constructor should take values for a, b, and c as parameters
• the constructor should also calculate the discriminant
• the boolean method hasSolutions() should identify whether solutions can be calculated
• the method getSolution1() should return the smaller of the two solutions, if one exists. (If one doesn’t exist, it should return the double value Double.NaN (“not a number”).
• the method getSolution2() should return the larger of the two solutions, if one exists. (If one doesn’t exist, it should return the double value Double.NaN (“not a number”).
