import javax.swing.joptionpane; import java.util.arrays;   public class report {  public static void main(string[] args) {         string[] listnames = gettutornames(); }  public static string[] gettutornames(listnames) {        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; } 

}

you have 2 errors:

1. you have define type listnames argument.

   public static string[] gettutornames(listnames) { //type of listnames?? 

2. your gettutornames needs pass argument:

   string[] listnames = gettutornames(); //argument here! 

looks need remove listnames argument gettutornames method.

public static string[] gettutornames() {     //code content... }
