how can i write a code that find square root without using math ?

1.

/*

2.

Find square root of a number using Math.sqrt

3.

This java example shows how to find square root of a given number using

4.

sqrt method of Java Math class.

5.

*/

6.

public class FindSquareRootExample {

7.

8.

public static void main(String[] args) {

9.

10.

/*

11.

* To find square root value of a number, use

12.

* static double sqrt(double d1) method Java Math class.

13.

*/

14.

15.

//returns square root of 9, i.e. 3

16.

System.out.println(Math.sqrt(9));

17.

18.

//returns square root of 25.5

19.

System.out.println(Math.sqrt(25.5));

20.

}

21.

}

22.

23.

/*

24.

Output would be

25.

3.0

26.

Here is a website that explains the algorithm for calculating sqrt without a math library.

if i use the System.out.println(Math.sqrt(25.5)); but instead putting a Double where the 25.5 is, will it work? because it doesn’t work for me:S
