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

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

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

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

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
