Raising a number to a power in Java -

here code. reason bmi not calculated correctly. when check output on calculator : (10/((10/100)^2))) 1000, in program, 5. i'm not sure doing wrong. here code:

import javax.swing.*;  public class bmi {     public static void main(string args[]) {         int height;         int weight;         string getweight;         getweight = joptionpane.showinputdialog(null, "please enter weight in kilograms");         string getheight;         getheight = joptionpane.showinputdialog(null, "please enter height in centimeters");         weight = integer.parseint(getweight);         height = integer.parseint(getheight);         double bmi;         bmi = (weight/((height/100)^2));         joptionpane.showmessagedialog(null, "your bmi is: " + bmi);     } } 

^ in java not mean raise power. means xor.

you can use java's math.pow()

and might want consider using double instead of int—that is:

double height; double weight; 

note 199/100 evaluates 1.
