Write a program that prints all real solutions to the quadratic equation ax2+bx+c=0. Read in a, b, c, and use the quadratic formula. If the discriminant b2-4ac is negative, display a message stating that there are no real solutions. Implement a class QuadraticEquation whose constructor receives the coefficients a, b, c, of the quadratic equation. Supply methods getSolution1() and getSolution2() that get the solutions, k, using the quadratic formula, or 0 if no solution exists. The getSolution1() method should return the smaller of the two solutions. If no solution exists, handle that with an else in your main, stating that no solution exists. (getSolution1 and getSolution2 will never be called because hasSolutions will be false. Supply a method boolean hasSolutions() that returns false if the discrimanant is negative. Make a tester class want the lowest number to print first.]
