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.

Java Programming, please solve the question Carefullyyyyy
In Java
Write a java program named: CoinConverter.java (Note: We do not need loops for this program.) This program will prompt the user for a number of cents, reading in the value from the keyboard. The number entered should be an integer. Using the value entered, calculate and print the number of quarters, dimes, nickels and/or pennies needed to achieve the value entered. If no coins of a denomination are needed, print O that value (e.g., if only quarters and pennies are needed, print "O dimes" and "O nickels"). Make sure you print only "quarter", "dime", "nickel" or "penny" when only 1 coin is required. NOTE: For full credit, place the user input on the new line (just use println in your prompt).

Write, Compile and Execute a Java program that prompts the user to enter a point (x, y) and checks whether the point is within the circle centered at (0, 0) with radius 10. For example, (4, 5) is inside the circle and (9, 9) is outside the circle, as shown in Figure below. (Hint: A point is in the circle if its distance to (0, 0) is less than or equal to 10. The formula for computing the distance is the square root of ((x₂-x₁)² + (x2 - y1)²). Test your program to cover all cases.) y-axis A (4,5) (0, 0) (9,9) Two sample runs are shown below. x-axis y-axis A (2,2) (0,0) Enter a point with two coordinates: 2 2 Enter Point (2.0, 2.0) is in the rectangle Enter a point with two coordinates: 6 4 Enter Point (6.0, 4.0) is not in the rectangle (6,4) x-axis
