Question

Transcribed Image Text: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.
