JAVAclass: Main.java, Quadratic.java, TestQuadratic.java
Create a class called Quadratic for representing a one-variable quadratic expression of the form:
ax2 + bx + c
a,b and c here are the coefficients.
The class should contain the following methods:
* A constructor that accepts values for a, b, and c.
* public double getA()
* public double getB()
* public double getC()
* public double evaluate (int x)
* will return the value of the expression at point x
* public double discriminant()
- that will return (b2 - 4ac)
* public boolean isImaginaryRoots()
- roots are imaginary if (b2 - 4ac) < 0
* public boolean isRealRoots()
- roots are real if (b2 - 4ac) >= 0
// these methods can only be invoked if the roots are not imaginary
* public float firstRoot()
* public float secondRoot()
* public boolean isPerfectSquare();
// If the first and second roots are equal
* Try to override the toString methods
* Write a sample main program that will work as shown below.
Example output:…
Find the error in each of the following code segments:
// Superclasspublic class Vehicle{private double cost;(Other methods . . .)}// Subclasspublic class Car extends Vehicle{public Car(double c){cost = c;}}
True or False
___(28) A class can extend multiple classes.
___(29) An interface in Java has no fields but methods to be implemented by other classes.
___(30) The key word private in defining a variable in a class limits the access to the variable by using only methods
