To Calculate the Power and Square Root of a Given Number

Here is a Java Program to Calculate the Power and  Square Root of a Given Number

import java.util.Scanner;

class power_sqrt {
 public static void main(String a[]){
    int power;
    float base;
        
  Scanner sc=new Scanner(System.in);  
  
  System.out.println("Enter the value of exponent");
  power=sc.nextInt();
  System.out.println("Enter the value for base");
  base=sc.nextFloat();
  number pow=new number();
  number sqr=new number();
  System.out.println("the value for power fun:-> "+pow.power(base, power));
  System.out.println("the value for square this is sqr of base:-> "+sqr.squre(base));
 } 
}

class number{
 float base;
 int expo;
 float power(float a,int b){
  if(b==1)
   return a;
  if(b==0)
   return 1;  
  else
   return(a*power(a,b-1));  
 }
 
 float squre(float base){  
  return base*base;  
 }
}

Output of Above Java Program
Enter the value of exponent
5
Enter the value for base
8
the value for power fun:-> 32768.0
the value for square this is sqr of base:-> 64.0
