Hi friend,

Code to help in solving the problem :

import java.io.*;
class Square
{
public static void main(String[] args) throws IOException
{
boolean boolexit=true;
do
{

final double smallValue = 1.0E-14 ;

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter the float value ");
double val = Double.parseDouble(br.readLine());

System.out.println("Do you want the (s)quare or square (r)oot of" + val);
String type=br.readLine();
if(type.equals("R") || type.equals("r"))
{

double N = val ;

if(N>0)
{
double guess = 1.00 ;

while ( Math.abs( N/(guess*guess) - 1.0 ) > smallValue )
{
// calculate a new value for the guess
guess = N/(2*guess) + guess/2 ;

}
System.out.println("The square root of "+N+" is "+ guess);
}
else
{
System.out.println("You must have a positive number for square root.");
System.out.println("Do you want the (s)quare or square (r)oot of" + val);
type=br.readLine();
}
}
if(type.equals("S") || type.equals("s"))
{
double sqval=val*val;
System.out.println("The number "+ val+" squared has the value "+ sqval);
}

System.out.println("Do you want to enter more data? y/n: y ");
String exit= br.readLine();
if(exit.equals("N") || exit.equals("n"))
{
boolexit=false;
}

}
while (boolexit);

}
}

Thanks
