Java program to calculate the power of a number
Read the base and exponent values from the user. Multiply the base number by itself and multiply the resultant with base (again) repeat this n times where n is the exponent value.
2 ^ 5 = 2 X 2 X 2 X 2 X 2 (5 times)
Example
import java.util.Scanner;
public class PowerOfNumber {
public static void main(String args[]){
Scanner sc = new Scanner(System.in);
System.out.println("Enter the base number ::");
int base = sc.nextInt();
int temp = base;
System.out.println("Enter the exponent number ::");
int exp = sc.nextInt();
for (int i=1; i<exp; i++){
temp = temp*temp;
}
System.out.println("Result of "+base+" power "+exp+" is "+temp);
}
}Output
Enter the base number :: 12 Enter the exponent number :: 2 Result of 12 power 2 is 144
