java - How to use the value returned from a method - 


    import java.util.scanner;  public class movies {    static scanner scan = new scanner(system.in);    static string movies[] = {"1. it\tp200", "2. battleship island\tp300", "3. annabelle creation\tp180", "4. woke this\t100"};    static string name;    static int seats=0;    static int number=0;     public static void getname(){         system.out.print("please enter name: ");         name = scan.nextline();         system.out.println("\nwelcome movieworld, " +name);         getmovietitle();      }  public static int getmovietitle(){      system.out.println("\nnow showing");    (string movie : movies) {        system.out.println(movie);    }    char choice;    system.out.print("would ticket? (y/n)");    choice= scan.next().charat(0);     switch(choice){         case 'y':         case 'y':             system.out.print("please select movie: ");             number = scan.nextint();             system.out.println("you have selected "+movies[number-1].substring(3,movies[number-1].length()));             getseats();             break;           case 'n':         case 'n':             system.out.println("thank you!");             system.exit(0);             break;         default:             getmovietitle();             break;     }     return number; }  public static int getseats(){     system.out.print("how many seats like? ");     int seat = scan.nextint();     system.out.printf("reserved # of seats %d ",seat );     return seat; }    public static void main(string[] args){     system.out.println("\tmovieworld");     system.out.println("________________________");     getname();      int mynum;     mynum=getmovietitle();     int mynum2;     mynum2=getseats();      int mov1 = 200;      int mov2 = 300;      int mov3 = 180;      int mov4 = 100;      int cost;      int money;      int change;      char c;      system.out.print("print receipt?(y/n)");      c= scan.next().charat(0);      switch(c){          case 'y':          case 'y':      if(mynum == 1){          cost=mov1*mynum2;          system.out.print("total: php"+cost);          system.out.print("received cash is: php");          money=scan.nextint();          change=money-cost;          system.out.print("your change is: php"+change);       }      else if(mynum == 2){          cost=mov2*mynum2;          system.out.print("total: php"+cost);          system.out.print("received cash is: php");          money=scan.nextint();          change=money-cost;          system.out.print("your change is: php"+change);      }      else if(mynum == 3){          cost=mov3*mynum2;          system.out.print("total: php"+cost);          system.out.print("received cash is: php");          money=scan.nextint();          change=money-cost;          system.out.print("your change is: php"+change);      }      else if(mynum == 4){          cost=mov4*mynum2;          system.out.print("total: php"+cost);          system.out.print("received cash is: php");          money=scan.nextint();          change=money-cost;          system.out.print("your change is: php"+change);      }      break;          case 'n':          case 'n':              system.out.println("thank you");              break;           default:               system.out.println("thank you");               system.exit(0);  } } }

i trying cost, money received , , change. having trouble in using returned values in methods. after selecting how many seats wanted program exits.

this values use in main method. first number

 system.out.print("please select movie: ");             number = scan.nextint();             system.out.println("you have selected "+movies[number-1].substring(3,movies[number-1].length()));             getseats();           case 'n':         case 'n':             system.out.println("thank you!");             system.exit(0);         default:             getmovietitle();      }     return number;

second seats can multiply number.

 public static int getseats(){     system.out.print("how many seats like? ");     int seats = scan.nextint();      return seats; }

  1. you need break:

    case 'y':     system.out.print("please select movie: ");     number = scan.nextint();     system.out.println("you have selected "+movies[number-         1].substring(3,movies[number-1].length()));     getseats();     break;

  2. you need assign number of seats global seats variable created in beginning of program, rather local variable.:

    public static int getseats(){  system.out.print("how many seats like? ");  seats = scan.nextint();   return seats; }

update:

  1. in updated question, you're capturing returned values of getmovietitle() , getseats() mynum , mynum2 in main method, still calling methods inside getname() , getmovietitle() respectively. comment calls:

    public static void getname(){    system.out.print("please enter name: ");    name = scan.nextline();    system.out.println("\nwelcome movieworld, " +name);    //getmovietitle();  }

    and

    case 'y':     system.out.print("please select movie: ");     number = scan.nextint();     system.out.println("you have selected "+movies[number-1].substring(3,movies[number-1].length()));     //getseats();     break;

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom...

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.
