Java issue with input -

-

today trying basic exercise , faced in problem : 

exception in thread "main" java.util.inputmismatchexception     @ java.util.scanner.throwfor(unknown source)     @ java.util.scanner.next(unknown source)     @ java.util.scanner.nextdouble(unknown source)     @ main.main(main.java:14)

this code :

import java.util.scanner;  public class main {     public static void main(string[] args) {         scanner input = new scanner(system.in);         double salary = 0;      // salary excluded tax         int tax = 0;            // % of tax         double taxtot = 0;      // amount of tax         double totsalary = 0;   // salary tax          system.out.println("salary, please : "); //input salary         salary = input.nextdouble();              if (salary <= 15000) {                          // <=15000             tax = 10;         } else if (salary>= 40000 && salary < 60000){       // >=40000             tax = 20;         } else {                                            // on > 60000             tax = 30;         }          taxtot = salary / 100*tax;         totsalary = salary - taxtot;         system.out.println("your tax : " + taxtot + " salary : " + totsalary);     } }

try example

scanner scanner = new scanner(system.in).uselocale(locale.us);

there difference between 5,0 , 5.0

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
