+//Objective: Create a file named src/Quadratic.java and write a program that calculates the roots of the quadratic
+// equation: $$ax^2 + bx + c = 0$$ using the quadratic formula: $$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
+//
+//Requirements:
+//
+//Prompt the user to input integers for (a), (b), and (c).
+//Compute the two solutions for (x) using the quadratic formula.
+//Display the results.
+//Additional Instructions:
+//
+//Your program should handle inputs where there is only one or no solution. Avoid division by zero or taking the s
+// quare root of a negative number.
+//Validate all inputs to prevent input mismatch exceptions.
+//Display specific error messages that include details about invalid input.
