    Default Finding the square root of a given integer using an algorithm

    I was given a lab in my programming class that asks us to use the algorithm
    xi+1=0.5(xi + n/xi) Xo= n/2, tofind thesquare root of the integer.
    the user supplies a parameter for the # of iterations. We were asked to overload the square root function by providinganother call that does thesame thingbut continues to iterate untilthecalculated value is less than a
    user provided errorvalue.

    Below is asample of thecode I am working on. I seem to be havingproblems compiling.

    public class SlowMath {

    private double n;
    private double num;
    private int i;
    private double a;

    // Scanner input = new Scanner (System.in);

    // Create application frame.





    public SlowMath(double n,double num,int i)
    {
    num=n/2;
    n=25;



    while(i<=10)
    {
    i=i+1;
    num=0.5*(num+n/num);
    }

    public void setN(double n)
    {
    n=25;
    }

    public double getN()
    {
    return n;
    }

    public void setNum(double num)
    {
    num=0.5*(num+n/num);
    }

    public double getNum()
    {
    return num;
    }

    /*
    public SlowMath(double n,double num,int n,double a)
    {
    a=n;
    double num=Math.sqrt(a);


    while(num!= )
    {
    num=num+1;
    num=0.5(num+n/num);
    }

    if(x=-1)
    System.out.println("Enter error value to stop: )


    }



    // Show frame


    */

    }
    }
    Please help!!

    Make a new topic and use code tags.
