Modify a class named Circle with fields named radius, diameter, and area. Include a constructor that sets the radius to 1 and calculates the other two values. Also include methods named setRadius() and getRadius(). The setRadius() method not only sets the radius, but it also calculates the other two values. (The diameter of a circle is twice the radius, and the area of a circle is pi multiplied by the square of the radius. Use the Math class PI constant for this calculation.) The TestCircle.java file has been provided to test your implementation. class Circle { privatedouble radius; privatedouble area; privatedouble diameter; Circle() { //Code here//

Concept explainers

Math class and its different methods

Java math class consists of arithmetic math methods that performs basic numeric operations such as finding the maximum or minimum of two values, rounding values, logarithmic functions, square root, and trigonometric functions, etc. The Math library functions can be accessed using the header Java.lang.Math. These math methods under Java math class are for our convenience.

I need to write a jave program to keep track of a team sport. Write a class, Team.java, that has the following: * two private instance variables: a String named color and an int named score. * a default constructor with no parameters that initializes color to "Red" and score to zero. * a constructor that takes two parameters (one for each instance variable) and sets the values of the instance variables. * a public getter and setter method for each instance variable. * a toString method that returns the color and score in the following format: "Red Team with 0 points."
Write a class called Circle that contains:a. Three private instance variables: radius (of the type double), color (of thetype String), and area (of type double).b. Two constructors - a default constructor with no argument (default value of radiusis 2.0, and color is Green) and a parameterized constructor, which initializes onlythe radius and the color variables.c. Getter and setter for the radius and color variables.d. Two public methods: calculateArea(), and getPerimeter, which return the areaand perimeter of a circle instance, respectively. Both methods have return.Then write a driver class that tests the Circle class. In the driver class, create two objectsof Circle class, one that tests the default constructor of the Circle class (here no user inputis required) and then get the color, radius, area, and perimeter of that object and displaythem. The second object should test the parameterized constructor (here you need to ask userto give you input to initialize the class variables).…
I need to override the toString() method with my own, however I am not sure how to reference back to the parameters for the constructor of the class. I've included my code below.

Create a class with the name 'QuadraticSolver'.The two roots of a quadratic equation of the form ??2 + ?? + ? = 0 can be obtained using the quadratic equation formula ?2 − 4?? is called the discriminant of the quadratic equation. If it is positive, the equation has two real roots. If it is zero, the equation has one root. If it is negative, the equation has no real roots. In the QuadraticSolver main method, write a program that prompts the user to enter values for a, b, and c and displays the result based on the discriminant. If the discriminant is positive, display the two roots. If the discriminant is 0, display one root. Otherwise, display the imaginary roots. Note that you can use Math.pow(x, 0.5) to compute √?. Here are three separate sample runs: 1.0, 3, 1The equation has two roots: -0.38 and -2.62 1, 2.0, 1The equation has one root: -1.00 1, -4, 8The equation has two imaginary roots: 2.00 + 2.00i and 2.00 - 2.00i
For this lab task, you will work with classes and objects. Create a class named text that works similar to the built-in string class. You will need to define a constructor that can be used to initialize objects of this new class with some literal text. Next, define three methods: to_upper() that will convert all characters to uppercase, reverse() that will reverse the text and length() that will return the length of the text. After you have completed this part, copy the following mainfunction to your code and check if the implementation is correct. int main() { text sample = "This is a sample text"; cout << sample.to_upper(); // This should display "THIS IS A SAMPLE TEXT" cout << endl;cout << sample.reverse(); // This should display "txet elpmas a si sihT"cout << endl; cout << sample.length(); // This should display 21 }

Write a class 'Cylinder' that has two fields: height and radius. The class should have only one parameterized constructor function to initialize these fields. The class should also have a method 'getVolume()' to calculate the volume of this cylinder. Now, create any 2 objects of this class with arbitrary values and show their volumes.
Please in pyth coding with correct indentation 4a) Given that you have a Liquid class that can be initialized with any amount of gallons, liters, ounces, etc, write the first line of the method that will allow you to add together two Liquid objects using operator overloading. Again, write ONLY the first line (method definition) – you do NOT have to write the entire method. 4b) Given that you have L1 and L2 which are instances of the Liquid class, write a line of code that uses operator overloading to add them together and assign the result to L3.
