Program Plan Intro

QuadraticEquation

Program plan:

  • Import required packages.
  • Define a class “Exercise09_10”
  • Declare the main class named “Main”.
    • Give the main method “public static void main ()”.
      • Prompt the user to get the inputs for the data members.
      • Create an object “equation”.
      • Print the statement “equation has no roots” if discriminant value is less than 0.
      • Print the result if value of discriminant is equal to 0 by calling the method “getRoot1()”.
      • Print the results if value of discriminant is greater than or equal to 0 by calling the methods “getRoot1()” and “getRoot2()”.
  • Define a class “QuadraticEquation”
    • Declare the data members and parameterized constructor.
    • Define a method to get the value of “a”.
    • Define a method to get the value of “b”.
    • Define a method to get the value of “c”
    • Define a method to get the value of discriminant.
    • Define methods to get the roots.
