Using the pow() method let’s calculate the following:
import java.lang.Math;class CalculatePower {public static void main( String args[] ) {//Calculating 5^4 and casting the returned double result to intint ans1 = (int) Math.pow(5,4);System.out.println("5^4 is "+ans1);//Calculating 1.5^3 and storing the returned double result to ans2double ans2 = Math.pow(1.5,3);System.out.println("1.5^3 is "+ans2);//Calculating 100^5 and casting the returned double result to intdouble ans3 = Math.pow(50,5);System.out.println("50^5 is "+ans3);}}
