Find power using math.pow() in java

• java.lang.Math.pow() method used to find the power of numbers.
• It is a static method define in Math class so that we can call directly using classname.
• Math.pow();
• It takes two double arguments and return type is double.

1. public final class Math extends Object

1. public static double pow(double a, double b)

Java Program to explain the usage of Math.pow() method in java

1. public class MathPow {
2.  
3.     /**

7. public static void main(String[] args) {
8.     
9.     
10.     double a = 3.0;
11.     double b = 4.0;
12.  
13.     
14.     System.out.println("Math.pow(" + a + "," + b + ")=" + Math.pow(a, b));
15.     System.out.println("Math.pow(" + b + "," + a + ")=" + Math.pow(b, a));
16.    
17.     System.out.println("Math.pow(4,2)="+Math.pow(4,2));
18. }
19.  
20. }

Output:

1. Math.pow(3.0,4.0)=81.0
2. Math.pow(4.0,3.0)=64.0
3. Math.pow(4,2)=16.0
