Question
Write a Java program that solves a set of quadratic equations as per Requirement #1 (without using global variables), and reads an integer number entered in the command line, as follows: > java program name input_number and depending on the value of this number does the following: 1) If the number entered is positive, the program shall solve (running in a loop) as many quadratic equations of the following form, as the input_number tells: a * x? + b * x+ c= 0 where coefficients a, b and c are double values, entered from the keyboard as per Requirement #3. 2) If the input number entered in the command line is not positive, the program shall print the following message to the screen and exit: A positive value shall be entered in the command line. 3) The values of coefficients a, b and c, as listed in Requirement #1, shall be read from the keyboard by the program with the following message on the screen, each time a new coefficient is needed: Please enter the next coefficient of a quadratic equation: 4) If the coefficient a is a zero, the program shall display the following message on the screen (first line) repeating the request for another value of a (second line): Coefficient a cannot be a zero. Enter the correct value. Please enter the next coefficient of a quadratic equation: 5) When the program solves the quadratic equation (calculates the roots), as per Requirement #1, the following output shall be displayed on the screen: <one empty line> Quadratic equation with the following coefficients a: <value>; b: <value>; c: <value> has the following roots: <root1> and <root2> 6) In case the quadratic equation for given coefficients does not have roots, the program shall print the following message, and continue operation for the next set of coefficients: <one empty line> Quadratic equation with the following coefficients: a: <value>; b: <value>; c: <value> does not have roots.
