someone pliz help have written this program but it does not display 2 to that power instead it asks to enter a power and when -1 is entered the program ends m missing out on something if someone could help then

import java.io.*;
class power
{
public static void main(String[] args)throws IOException
{
int count = 0;
int power;
int exponent = 2;
double result = 1;

BufferedReader Keyboard=new BufferedReader( new
InputStreamRead er(System.in));

power = Integer.parseIn t(Keyboard.read Line());

while (count < exponent)
{
result = result * 2;
count = count +1;
}



}

}

Use a suitable Thread Title and use Code Tags while you do Post according to Reply Guidelines.
use exit(0) or break statement from a loop.
Good luck.

I edited your thread title. About your problem: you don't print anything after that
while loop so you can't know what exactly happened. Without actually thinking
about your problem I can see that none of the code actually does something with
variable 'power', i.e. it could've been left out altogether.

kind regards,
