In this tutorial we will learn writing Java Program to calculate Power of integer using POW() method.
POW() method in Java
java.lang.Math.pow() In java, pow() method takes two parameter as an input and return the calculated Power as an Output.
For Example:
Math.pow(x, y) where x is base and y is exponent. so for the input pow(5,3) output will be 5*5*5= 125.
Java Program to calculate Power using POW() method
import java.util.*;
public class Main {
public static void main(String[] args) {
int base,exponent;
Scanner sc = new Scanner(System.in);
System.out.println("Please give the base number");
base= sc.nextInt();
System.out.println("Please give the exponent number");
exponent= sc.nextInt();
System.out.println(base+" to the power "+exponent);
double result = Math.pow(base, exponent);
System.out.println(result);
}
}
Output
Please give the base number
5
Please give the exponent number
3
5 to the power 3
125.0
Explanation
For the input from the user, the base number is 5, and the exponent number is 3. The ‘Math.pow(5, 3)’ will be 125, which is 6x6x6x6 i.e. 216.
