Java using Eclipse

Write a program that uses the following subroutine to solve equations specified by the user.

/** * Returns the larger of the two roots of the quadratic equation * A*x*x + B*x + C = 0, provided it has any roots. If A == 0 or * if the discriminant, B*B - 4*A*C, is negative, then an exception * of type IllegalArgumentException is thrown. */ static public double root( double A, double B, double C ) throws IllegalArgumentException { if (A == 0) { throw new IllegalArgumentException("A can't be zero."); } else { double disc = B*B - 4*A*C; if (disc < 0) throw new IllegalArgumentException("Discriminant < zero."); return (-B + Math.sqrt(disc)) / (2*A); } }

Your program should allow the user to specify values for A, B, and C.

It should call the subroutine to compute a solution of the equation.

If no error occurs, it should print the root. However, if an error occurs, your program should catch that error and print an error message.

After processing one equation, the program should ask whether the user wants to enter another equation.

The program should continue until the user answers no.
