this question has answer here:

i've got simple question i've got complete tomorrow. code compiles , runs exception error. sorta kinda new java , have feeling related multidimensional array. 

package question12;  import java.security.securerandom; import java.util.scanner;    public class question12  {  scanner sc = new scanner(system.in);  string first_name, last_name, id, seat_no; char seatch; string[][] passengerlist = new string[1][4];  void setfname() {     system.out.printf("passenger first name: ");     first_name = sc.nextline(); }  void setlname() {     system.out.printf("passenger last name:  ");     last_name = sc.nextline(); }  void setid() {     system.out.printf("passenger id:         ");     id = sc.nextline(); }  void setseatnumber () {     string ticket, stringrandnum;     string alfabet = "abcdefghijklmnopqrstuvwxyz";     int seatcharnum, seatintnum;      securerandom randomn = new securerandom();      seatintnum = randomn.nextint(120);     seatcharnum = randomn.nextint(7);      seatch = alfabet.charat(seatcharnum);      seat_no = "" + seatintnum;   }  void generateticket() {      (int = 0; < 39; i++)     {         if (i == 19)         {             system.out.printf("air kzn");         } else             system.out.print('*');     }      system.out.println("");      system.out.printf("*you seated in seat number: %s%s%n", seatch, seat_no);     system.out.printf("*passenger name: %s\n", first_name);     system.out.printf("*passenger surname: %s%n", last_name);     system.out.printf("*passenger id: %s%n", id);      (int = 0; < 39; i++)     {         if (i == 19)         {             system.out.printf("air kzn");         }          system.out.print('*');     }       system.out.println("");  }  void storevalues() {     passengerlist[0][0] = first_name;     passengerlist[0][1] = last_name;     passengerlist[0][2] = id;     passengerlist[0][3] = seat_no; }  void printpassengerlist() {     system.out.printf("passenger name   passenger surname   passenger id    seat number\n");      (int = 0; < 40; a++)         system.out.print('-');      (int c = 0; c < passengerlist.length; c++)         (int d = 0; d < passengerlist[d].length; d++)         system.out.print(passengerlist[d][c]); }  public static void main(string[] args)  {      question12 q12 = new question12();      q12.setfname();     q12.setlname();     q12.setid();     q12.setseatnumber();     q12.generateticket();     q12.storevalues();     q12.printpassengerlist();      }  }

you have:

for (int c = 0; c < passengerlist.length; c++)     (int d = 0; d < passengerlist[d].length; d++)         system.out.print(passengerlist[d][c]);

this give error because of 2 reasons:

  • your inner loop should have passengerlist[c].length instead of passengerlist[d].length.

  • your printout should passengerlist[c][d] instead of passengerlist[d][c}.

change this:

for (int c = 0; c < passengerlist.length; c++)     (int d = 0; d < passengerlist[c].length; d++)         system.out.print(passengerlist[c][d]);
