Design a class named QuadraticEquation for a quadratic equation ax² + bx+c= 0. The class contains: ▪ Private data fields a, b, and c that represent three coefficients. ▪ A constructor with the arguments for a, b, and c. ▪ Three getter methods for a, b, and c. ▪ A method named getDiscriminant () that returns the discriminant, which is b² - 4ac. ▪ The methods named getRoot1 () and getRoot2() for returning two roots

Question
Design a class named QuadraticEquation for a quadratic equation ax²+bx+c = 0. The class contains: ■ Private data fields a, b, and c that represent three coefficients. ▪ A constructor with the arguments for a, b, and c. ▪ Three getter methods for a, b, and c. ▪ A method named getDiscriminant () that returns the discriminant, which is b² - 4ac. ■ The methods named getRoot1 () and getRoot2 () for returning two roots of the equation r1= -b+√√√b² - 4ac 2a and r₂ = -b-√√b² - 4ac 2a These methods are useful only if the discriminant is nonnegative. Let these methods return 0 if the discriminant is negative. Draw the UML diagram for the class then implement the class. Write a test program that prompts the user to enter values for a, b, and c and displays the result based on the discriminant. If the discriminant is positive, display the two roots. If the discriminant is 0, display the one root. Otherwise, display "The equation has no roots."
