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?

");     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:

3. 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;
