## How do you calculate roots in Java?

**Java program to find the roots of a quadratic equation**

- Calculate the determinant value (b*b)-(4*a*c).
- If determinant is greater than 0 roots are [-b +squareroot(determinant)]/2*a and [-b -squareroot(determinant)]/2*a.
- If determinant is equal to 0 root value is (-b+Math.sqrt(d))/(2*a)

## What do you call the positive nth root of a number?

Every positive real number x has a single positive nth root, called **the principal nth root**, which is written. . For n equal to 2 this is called the principal square root and the n is omitted. The nth root can also be represented using exponentiation as x^{1}^{/}^{n}.

## What is root in Java?

**The Object class of the java.** **lang package** is the root class in Java i.e. It is the super class of every user-defined/predefined class n Java. … The reason for this is to have common functionalities such as synchronization, garbage collection, collection support, object cloning for all objects in Java.

## How do you square something in Java?

## How do you multiply pi in Java?

To get the area, we need to multiply pi times the radius squared.

…**An Example**

- import java. lang. Math. *;
- public class Pie {
- public static void main(String[] args) {
- //radius and length.
- double radius = 5;
- double len = 15;
- // calculate the area using PI.
- double area = radius * radius * Math. PI;

## How do you create a floor in Java?

floor(double a) returns the largest (closest to positive infinity) double value that **is less than or equal** to the argument and is equal to a mathematical integer. Special cases: If the argument value is already equal to a mathematical integer, then the result is the same as the argument.

## How can I get log in Java?

**The java.**

**lang.**

**Math.**

**log**(double a) returns the natural logarithm (base e) of a double value.- If the argument is NaN or less than zero, then the result is NaN.
- If the argument is positive infinity, then the result is positive infinity.

## What is array in Java?

An array is **a container object that holds a fixed number of values of a single type**. The length of an array is established when the array is created. After creation, its length is fixed. … Each item in an array is called an element, and each element is accessed by its numerical index.
