Question

I want to create a program that calculates the square root of a number without using Math.sqrt

Answer 1

You can do something like this:

public static void calcRoot(){

    double num=9;

    double guess=0;

    double result=6;

    while(Math.abs(guess-result)!=0){

        guess=result;

        result=(guess+(num/guess))/2;       

    }

System.out.print(result);

}
