Error recieved when compiling - AreaCalculationProgram.java:23: error: incompatible types: possible lossy conversion from double to int -

-

so, here code. calculates area of circle.

import java.util.*; public class areacalculationprogram { public static void main(string [] args)

    {        //code circle        int radius, areaofcircle, area;      scanner sc = new scanner(system.in);      system.out.print("enter diameter of circle");      double diameter = sc.nextdouble();      integer intdiameter = sc.nextint();      diameter = intdiameter.doublevalue();      areaofcircle = (int) math.pow((diameter/2),2 ) * math.pi;      system.out.print("areaofcircle" + area);

shown below error get:

areacalculationprogram.java:23: error: incompatible types: possible lossy conversion double int     areaofcircle = math.pow((diameter/2),2 ) * math.pi;                                               ^

why areaofcircle int? problem requirement? should use round/floor/ceil math class methods (depends)

i'm using react-router first time , don't know how think in yet. here's how i'm loading components in nested routes. entry point .js reactdom.render( <router history={hashhistory} > <route path="/" component={app}> <route path="models" component={content}> </route> </router>, document.getelementbyid('app') ); app.js render: function() { return ( <div> <header /> {this.props.children} </div> ); } so child of app content component sent in. i'm using flux , app.js has state , listens changes, don't know how pass state down this.props.children. before using react-router app.js defines children explicitly, passing state natural don't see how now. using couple of react helper methods can add state, props , whatever else this.props.children render: function() { var children = react.ch...
