java - Multiple inputs with arrays using String - Names -

i need write program have user enter list of tutor names. 10 peer tutors may hired. then, program present each name, based on list alphabetized last name. have far, not work , don't know do. need continue run until stop , continue more of program.

import javax.swing.joptionpane; import java.util.arrays;   public class report {      public static void main(string[] args) {            int numtutors = 10;           string[] listnames = gettutornames();     }      public static string[] gettutornames() {            string firstname;         string lastname;         string[] listnames = new string[10];          (int x = 0; x < listnames.length; x++) {             firstname = joptionpane.showinputdialog(null, "enter tutor's first name: ");             lastname = joptionpane.showinputdialog(null, "enter tutor's last name: ");              if (firstname.equals("")) &&  lastname.equals("")) {                 break; // loop end             }             listnames[x] = lastname + ", " + firstname;         }         return listnames;     } } 

well, first. intellij didn't format code correctly when edited it, , discovered hit-list of errors. bear in mind - code won't compile, let alone run, until these fixed.

• int numtutors comes out of nowhere. if want define it, outside of method call , set appropriate value.

  public static void main(string[] args) {     int numtutors = 10;     string[] listnames = gettutornames(numtutors); } 

• these declarations invalid:

  string = firstname; string = lastname; 

  you need sort of variable name in between string , =.

  you're not matching contract you're passing in gettutornames - either pass in or accept must change. i'm thinking it's latter.

• you can't use == compare string. have use .equals(). leads me to...

• your break outside of loop. move inside of loop.

  for (int x = 0; x < listnames.length; x++) {     firstname = joptionpane.showinputdialog(null, "enter tutor's first name: ");     lastname = joptionpane.showinputdialog(null, "enter tutor's last name: ");     if (firstname.equals(" "))&&lastname.equals(" ")){         break; // loop end     } } 

  ..and that leads me to...

• you don't put values anywhere through loop! you're running same code ten times! place them array.

  // after check see if firstname , lastname blank listnames[x] = firstname + lastname; // don't know want them here. 

• there no .add() array. above how enter elements array.

• your return outside of method block entirely. move method.

now, these issues find. work on compilation issues first, 1 may talk errors in code logic. if can, snag quiet moment , ensure understand variable declaration , string comparison. strongly recommend reading material found in the java wiki tag.
