# Exponentiation of a number in java

Although there is no simple exponential Java operator, you can easily calculate the exponent using several different methods. Using powerinJava (Math.pow) is the most flexible and simple approach. You need to import the java.lang.math class before calculating the degree score. It's a simple line of code, and the function itself has an easy-to-use syntax.

Alternative methods use a for loop or a recursive call, but they only work for degrees greater than or equal to 1, so you should try to use the former where possible.

## Math.pow in Java

The core of the Java scoring method is the math.pow() function, which takes two values and calculates one to the power of the other. Thanks to this syntax, you can raise any number to any power. To make the result an integer, use (int) before the function. Without this, it automatically returns the value "double" and accepts the parameters as well as "double".

## Calculating the Exponent

The process of calculating the Java score basically involves only the use of this function. For example, open your Java IDE – Netbeans. For the first line of code, you import the class before performing the calculation, so type "importjava.lang.math;" (without quotation marks) before proceeding to the calculation. On the next line, enter "class" and something descriptive after the space, such as "CalculatePower {" with an open parenthesis at the end, to prepare for the rest of the code.

On a new indented line, write "public static void main( Stringargs[] ) {" (again without quotation marks), and then continue the calculation. Depending on the type you want to return—for example, integer values or double values—type "int" or "double" at the beginning of the new indented line.

Next, enter something descriptive to answer, such as "ans", and then "= (int) Math.pow(base, exponent)", noting that if you are using double values, enter "(double)" instead of "(int)" after the equal sign.

Finally, type "System.out.println(+ans)" on another new line, and then run the command to calculate the degree score.

As always, you enter the numbers you want to use instead of "base" and "exponents." So if you want to calculate 52 as an integer, then your code should say:

import java. yaz.. Mathematics;

public class Power calculation {

public static void main( String args[] ) {

intans = (int) Math.pow(5,2);

The system.from. println (+ans) method);

}

}
