Java Program to Find square root of a Number without sqrt.

import java.util.Scanner;
class JavaExample { 

    public static double squareRoot(int number) {
 double temp;

 double sr = number / 2;

 do {
  temp = sr;
  sr = (temp + (number / temp)) / 2;
 } while ((temp - sr) != 0);

 return sr;
    }

    public static void main(String[] args)  
    { 
 System.out.print("Enter any number:");
 Scanner scanner = new Scanner(System.in);
 int num = scanner.nextInt(); 
 scanner.close();

 System.out.println("Square root of "+ num+ " is: "+squareRoot(num));
    } 
}
